A Florida police sergeant was fired for offering Trayvon Martin shooting targets to his colleagues, authorities said Saturday.

Sgt. Ron King of Port Canaveral Police Department was fired Friday after two officer allegedly refused to use the targets for firearm training. One of those officers filed a complaint against him, which prompted an internal review.

In a response posted to YouTube late Saturday, King denied the accusations against him. King said the allegation that he offered the targets to others to shoot at was a "complete fabrication."

The politically-charged shooting targets were meant "to use a bad situation as a learning tool," he claimed.

Seventeen-year-old Martin was shot and killed in Sanford, Florida, by George Zimmerman in February 2012. Zimmerman said he shot the unarmed teen in self-defense.

Following the incident, shooting targets designed to resemble Martin began appearing on the Internet. The black targets show a figure wearing a hoodie with skittles in his pocket and crosshairs over his chest.

"It is absolutely reprehensible that a high-ranking member of the Port Canaveral Police, sworn to protect and serve Floridians, would use the image of a dead child as target practice," Martin family attorney Ben Crump said in a statement. "Such a deliberate and depraved indifference to this grieving family is unacceptable."
