Palmetto man is found guilty of a deadly shooting — and then abusing the body

Palmetto man is found guilty of a deadly shooting — and then abusing the body.

By Michael Moore Jr.,

A Manatee County jury has convicted a 43-year-old Palmetto man on charges related to the 2018 fatal shooting and burning of Antonio Bradley.

Aaron David Koziak was found guilty Wednesday of second-degree murder with a firearm and abuse of a human body. The jury deliberated for about 2 1/2 hours, with the verdict coming after a three-day trial presided over by Circuit Court Judge Frederick Mercurio at the Manatee County Judicial Center in downtown Bradenton.

A sentencing hearing will be held at a later date, likely sometime in January, Mercurio said.
The maximum sentence for second-degree murder in Florida is life in prison and the mandatory minimum for second-degree murder with a firearm is 25 years. The maximum penalty for abuse of a body, which is a second-degree felony, is 15 years in prison.
Sometime before the trial, the State Attorney’s Office offered Koziak and his defense lawyer, Jaime Garcia, a plea deal of 30 years, but the offer was rejected. Koziak was previously denied the use of Florida’s “Stand Your Ground” law as his defense against the murder charge.

How the crime unfolded

He told investigators shortly after his arrest that he fatally shot the 35-year-old Bradley in the head on Nov. 14, 2018 , before taking his body to MJ Road near Myakka City and setting it on fire.

When detectives arrived around 11:20 p.m. after a witness saw the fire and called 911, they found Bradley’s body on a pile of smoldering logs in the drizzling rain.

Firefighters arrived and put out the flames, but Bradley’s body had been severely burned.
Dr. Phoutthasone Thirakul, the medical examiner who did the autopsy on Bradley, testified in court Tuesday that he had burns to around 75% of his body, although she said it was a gunshot wound to his right temple that proved to be fatal.

In the courtroom

Prosecutors said Bradley had already been dead for hours before the burning. Images of Bradley’s burned body were shown in the courtroom on Tuesday. His mother, Yolanda Charles, clutched a tissue and closed her eyes while some of the photos were shown, before she eventually left.

Koziak and his attorneys argued that the shooting was in self-defense. He told detectives that Bradley was his drug dealer and that he owed him money. As a result of this debt, Bradley would often borrow Koziak’s 2016 gray Ford F-150 for extended periods.

Was there a fight?
He said the two had gotten into a fight the night of the shooting when Bradley grew frustrated over the situation. He said while the two were rolling around on the ground, a gun fell out of Bradley’s “baggy basketball shorts” and onto his stomach. Koziak said he picked up the gun and shot Bradley in defense.

But prosecutors said there is no evidence of a fight, pointing to the neatness of his shirt in security footage captured after the shooting. Prosecutors also pointed to Koziak never saying any punches were thrown.

Prosecutors say they believe the killing took place between 7:04 and 7:12 p.m. based on security footage at the house of Lawrence Shackelford, a friend of Koziak’s.

The night of the killing

Frames were missing from the security footage and were unable to be recovered, prosecutors said. Shackelford later testified that Koziak had told him after the shooting that he was capable of removing frames from the security footage but was unsure if he had done so.

Koziak had been staying at Shackelford’s house for some time, he testified Tuesday. The two worked together installing security systems.
Shackelford said he got a call from Koziak just before 8 the night of the killing saying that he had shot someone.

When he arrived at his house, he said Koziak looked “panicked and flustered” and had bruising on his chest and hands. Photos showing some of that bruising were shown in the courtroom during closing arguments Wednesday afternoon.
“Did he look like he had been in a fight?” the defense asked Shackelford. “Yes,” he said.

He also said that Koziak’s shirt was torn and bloody. Prosecutors said that if his shirt had any blood on it at any point, it was likely from when Koziak, with Shackelford’s help, loaded Bradley’s body into the bed of his pickup truck.

Koziak drove around for an extended period of time before video footage showed him stopping at a Circle K near Moccasin Wallow Road in Palmetto to purchase a container of gasoline around 9:15 p.m.

Prosecutors say the truck and the drug debt were a source of growing tension between the two.

“He doesn’t wanna do it anymore, he was over having a debt and this was the way out of this debt,” said Rebecca Freel, the assistant state attorney.

But the defense argued that Koziak felt threatened by Bradley, who they say grew increasingly frustrated by not getting his money.
Text messages exchanged between the two about money and the truck were submitted as evidence in court, including text messages sent from Bradley’s phone hours after his body was already discovered.

Prosecutors say these texts were sent by Koziak from Bradley’s phone to himself to make it seem like he was being threatened.
Koziak told detectives in an interview that he took Bradley’s two phones after the shooting and and tossed them. One was found on the north side of State Road 70, about two miles away from the block of MJ Road where Bradley’s body was discovered. The other phone was never recovered.

Koziak also told detectives that he cut the firearm used in the shooting into pieces with a hacksaw and threw it into water off of multiple bridges.

Detectives have not recovered a firearm.

USCCA Range Safety Officer Ric S. and Student Why You Should Consider Owning a Firearm Gregg Kielma Kielma writes, Let's take a LOOK at responsible firearm ownership and why owning a firearm make sense. My thoughts. As a Responsible, Empowering Choice for Personal Safety and Skill Development , firearm ownership is a personal decision — one that carries both responsibility and tremendous potential benefits. When approached with proper training and a commitment to safety, owning a firearm can strengthen your confidence, enhance your preparedness, and connect you with a community of responsible, like-minded individuals. Personal Protection and Peace of Mind, a firearm can serve as an effective tool for personal and home defense. While no one wants to face a dangerous situation, being prepared provides reassurance. Responsible firearm ownership gives many people the confidence that they can protect themselves and their families if the need ever arises. Training Builds Confidence, owning a firearm encourages discipline, education, and skill development. With professional instruction — the kind we provide at Tactical K Training — new and experienced shooters alike learn safe handling, situational awareness, and sound decision making. These skills build confidence that extends far beyond the range. A Skill Driven Rewarding Hobby, shooting sports are one of the fastest growing recreational activities in the country. Whether you enjoy target shooting, competition, or simply improving your accuracy, firearms offer a hobby that is both challenging and deeply satisfying. Many shooters find the focus and discipline of training to be relaxing and rewarding. Promoting Responsibility and Preparedness, firearm ownership reinforces the importance of responsibility. Safe storage, regular maintenance, and ongoing training cultivate habits that benefit every aspect of life. Preparedness isn’t about fear — it’s about being capable, informed, and ready for the unexpected. E xercising a Constitutional Right, for many Americans, firearm ownership is also about embracing a fundamental liberty. Exercising this right responsibly helps preserve it for future generations and supports the values of independence and self-reliance. Strengthening Community Through Education, responsible firearm owners often become advocates for safety and education. By promoting secure storage, encouraging proper training, and sharing knowledge, they help create safer communities and reduce preventable accidents. Education is the foundation of responsible ownership. Gregg Kielma’s Final Thoughts Owning a firearm is a meaningful choice one that can enhance your safety, build your confidence, and connect you with a community committed to responsibility and skill. With the right training and mindset, firearm ownership becomes not just a tool, but a path to empowerment Gregg Kielma

Tactical K Training and Firearms A GunSkins Dealer and Professional Installer The Benefits of Gun Skins: Protection, Personalization, and Practicality Gregg Kielma In recent years, gun skins—vinyl wraps were designed to cover and protect a firearm’s exterior—have become increasingly popular among shooters of all backgrounds. While some view them as purely cosmetic, gun skins offer a range of practical benefits that go far beyond appearance. For many responsible gun owners, they’ve become a smart investment in both function and longevity. Tactical K Training and Firearms is a GunSkins Dealer and professional installer. Call me if you're interested in giving your firearm a new look! Below are my thoughts on GunSkins and the benefit of protecting your firearm and the versatility of changing the look when you desire. Kielma says, Let's Take a LOOK 1. Enhanced Protection for Your Firearm Firearms are tools, and tools see wear. Whether you’re training regularly, carrying daily, or storing a firearm in challenging environments, the finish can take a beating. Gun skins help by: • Shielding the firearm’s exterior from scratches, scuffs, and minor abrasions • Adding a layer of protection against moisture and corrosion • Preserving the original finish, which helps maintain long-term value For shooters who train hard or carry often, this protective layer can make a noticeable difference over time. 2. Customization Without Permanent Modification One of the biggest advantages of gun skins is the ability to personalize a firearm without committing to a permanent change. Unlike Cerakote or engraving, skins can be: • Applied quickly • Removed cleanly • Swapped out for new designs as preferences change This makes them ideal for shooters who want a unique look without altering the firearm’s factory finish. 3. Improved Grip and Handling Many gun skins add a subtle texture that enhances grip without being overly aggressive. This can be especially helpful in: • Wet or humid environments • High-stress training scenarios • Situations where gloves are worn Better grip means better control, and better control means safer, more consistent shooting. 4. Camouflage and Field Utility For hunters and outdoorsmen, gun skins offer practical concealment benefits. A well-chosen pattern can: • Break up the outline of the firearm • Reduce glare • Blend the firearm into specific environments (woodland, desert, marsh, etc.) This is particularly valuable for hunters who want every advantage in the field. 5. Cost-Effective Aesthetic Upgrades Compared to refinishing or custom coatings, gun skins are an affordable way to refresh the look of a firearm. They allow owners to: • Modernize older firearms • Match gear or loadouts • Create themed builds without high costs It’s a simple upgrade that delivers a big visual impact. 6. Easy Maintenance and Reversibility Gun skins are designed to be durable but removable. If a skin becomes worn or damaged, it can be replaced without affecting the firearm underneath. This makes maintenance straightforward and stress-free. Is GunSkins Right for YOU? Kielma's Final Thoughts Gun skins offer a blend of protection, personalization, and practicality that appeals to both new shooters and seasoned professionals. Whether you’re looking to preserve your firearm, enhance its performance, or simply give it a fresh look, gun skins provide a flexible and cost-effective solution.

Understanding .380 ACP, 9mm, and .45 ACP: A Practical Comparison for Modern Shooters Gregg Kielma The right caliber depends on your needs and shooting style. Your choice affects recoil and muzzle flip, both of which you must manage for accuracy. Let's Take a LOOK Handgun calibers have evolved dramatically over the last century, but three cartridges continue to dominate the conversation for personal protection and everyday carry: .380 ACP, 9mm, and .45 ACP. Each brings its own strengths, limitations, and ideal use cases. Whether you’re a new gun owner, a concealed carrier, or a student in a defensive pistol class, understanding how these calibers differ helps you make informed, confident decisions. .380 ACP: Compact, Manageable, and Purpose Built for Concealment Introduced by John Browning in 1908, the .380 ACP (also known as 9mm Short or 9mm Browning) was designed for small, lightweight pistols that are easy to conceal. Its mild recoil and compact firearm platforms make it a popular choice for those who prioritize comfort and concealability. Strengths • Low recoil, easy to control under stress • Ideal for pocket pistols and ultra compact carry guns • Comfortable for new shooters or those sensitive to recoil Limitations • Lower velocity and energy compared to 9mm and .45 ACP • Reduced penetration and expansion, depending on ammunition choice • Best suited for close range defensive encounters Despite its smaller size, modern ammunition has improved the .380’s performance, making it a viable defensive option when shot placement and training are prioritized. 9mm Luger: The Modern Standard for Defense and Duty The 9mm has become the dominant defensive handgun caliber worldwide — and for good reason. It offers an excellent balance of recoil, capacity, and ballistic performance. Modern hollow point technology has significantly improved its effectiveness, narrowing the gap between 9mm and larger calibers. Strengths • Manageable recoil with fast follow up shots • Higher magazine capacity compared to .45 ACP • Wide availability and lower cost • Strong performance with modern defensive ammunition Limitations • Slightly more recoil than .380 ACP • Performance varies depending on barrel length and ammo selection For most shooters, 9mm represents the best blend of shootability, effectiveness, and practicality. It’s the go to choice for law enforcement, military, and civilian carriers alike. .45 ACP: Heavy, Slow, and Proven Developed in 1904, the .45 ACP has earned a legendary reputation for its stopping power and large permanent wound channels. It fires a heavy 230 grain bullet at moderate velocity, producing a distinct recoil impulse that experienced shooters often describe as a “push” rather than a “snap.” Strengths • Large bullet diameter and strong terminal performance • Consistent expansion with modern hollow points • Long history of reliability in defensive use Limitations • Lower magazine capacity • Heavier recoil, especially in compact pistols • Larger, heavier firearms While 9mm has become the modern standard, .45 ACP still appeals to shooters who prefer a big bore option and are comfortable managing its recoil. Side by Side Comparison .380 ACP 9mm .45 ACP Recoil Light Moderate Heavy Capacity High (small gun) High Lower Penetration Lowest Strong Strong Expansion Moderate Strong Very strong Usage Deep concealment General carry Big bore carry, home defense Which Caliber Is “Best”? There is no universal best caliber — only the best caliber for the shooter and the mission. As the sources emphasize, choosing between .380, 9mm, and .45 ACP depends on factors like recoil tolerance, firearm size, concealment needs, and personal comfort. Kielma's General Guidance and Parting Shot • Choose .380 ACP if you need maximum concealability and minimal recoil. • Choose 9mm if you want the best all around defensive option with excellent capacity and performance. • Choose .45 ACP if you prefer a heavy hitting round and don’t mind a larger gun.

How to Pick the Right Firearm: A Smart, Safe Approach for New Owners, Students and The Seasoned Shooter Gregg Kielma As an FFL and Firearms Instructor, students or prospective new firearm owners ask me, what's the best gun for me? That's not a difficult question to answer, however, it's one that needs questions answered to pick the correct caliber that's the perfect fit for you and your shooting styles. Choosing a firearm is a personal decision that blends purpose, comfort, and responsibility. With so many options on the market, the process can feel overwhelming—but a thoughtful, structured approach makes it far easier and far safer. Start With Your Purpose • Every good decision begins with why. Your intended use will narrow the field quickly: • Home defense often calls for simplicity, reliability, and ease of use. • Concealed carry requires a firearm that balances concealability with shootability. • Hunting or sport shooting may demand specific calibers, barrel lengths, or action types. • Training and skill development might prioritize ergonomics and affordability. • Knowing your purpose prevents impulse buys and ensures the firearm truly fits your needs. Fit and Comfort Matter • A firearm should feel like an extension of your hand. When evaluating options: • Check the grip size and angle. • Ensure you can reach the controls naturally. • Pay attention to weight and balance. • Look for a sight picture that feels intuitive. • If it’s uncomfortable in the store, it won’t magically improve on the range. Test Before You Buy • Whenever possible, shoot the firearm before purchasing. Many ranges rent popular models, giving you a chance to evaluate: • Recoil management • Trigger feel • Accuracy and control • Overall confidence and comfort • Real-world experience beats guessing every time. Prioritize Safety and Training • The “right” firearm is only as effective as the person using it. Responsible ownership includes: • Learning safe handling habits • Understanding your firearm’s operation • Practicing regularly • Storing it securely • A well chosen firearm paired with proper training is the foundation of safe, confident ownership. Reliability and Quality Purchase a firearm with a reputable history that's known for durability and consistent performance. A reliable firearm isn’t just a preference—it’s a necessity. If you're looking to purchase a firearm, please give me a call to set up an appointment to get the perfect fit for your style and needs. Gregg Kielma 941 737-6956

Home and Business Security & Safety: Building Peace of Mind Gregg Kielma Kielma advises, security is more than locks and alarms, it’s about creating an environment where people feel safe, prepared, and confident. Whether protecting your family at home or safeguarding your business, proactive measures make all the difference. Let’s take a LOOK. Home Security Essentials • Layered Protection: Combine physical barriers (locks, reinforced doors, secure windows) with modern technology (cameras, alarms, smart sensors). • Lighting Matters: Motion-activated exterior lights deter intruders and increase visibility around entry points. • Secure Entry Points: Deadbolts, strike plates, and reinforced garage doors add critical layers of defense. • Family Awareness: Teach household members to lock doors, verify visitors, and practice situational awareness. Business Security Priorities • Access Control: Use keycards, codes, or biometric systems to limit entry to authorized personnel. • Surveillance Systems: Modern cameras provide real-time monitoring and cloud storage for evidence if needed. • Employee Training: Staff should know emergency procedures, recognize suspicious activity, and understand their role in maintaining safety. • Cybersecurity Integration: Protect digital assets with strong passwords, firewalls, and regular updates—physical and digital security go hand in hand. The Human Factor Technology is powerful, but people make the difference. Responsible security practices, situational awareness, and ongoing training ensure preparedness for the unexpected. At Tactical K Training and Firearms, we emphasize education and readiness so our clients can protect what matters most, safely and responsibly.
