A police officer accused of bringing targets resembling Trayvon Martin to a gun range has been fired.

Port Canaveral Interim Chief Executive Officer John Walsh told WFTV on Saturday that Sgt. Ron King was leading a target practice with two other Port Canaveral police officers and a civilian port employee when he pulled out the targets April 4. Walsh says King asked the group if they wanted to use the targets and they said no, telling King to put them back into his patrol car.

Port Canaveral is about 50 miles southeast of Sanford, where the 17-year-old Martin was killed in 2012 by neighborhood watch volunteer George Zimmerman.

Zimmerman says he shot Martin in self-defense. His trial is set for June.
