Police say a 12-year-old Florida boy is under arrest and accused of fatally shooting a homeless man in the head.

Jacksonville Sheriff's Office Assistant Chief Chris Butler said Thursday that the boy was arrested in the killing of 54-year old Thomas Trent.

The State Attorney's Office has not yet filed charges in the case.

Trent's body was found June 28 at a vacant business building.

Butler says surveillance video from a nearby dental care office and a tattoo business showed two young men walking near the site of Trent's slaying at 2:25 a.m.

A sheriff's arrest report shows that the other boy in the video -- identified as a 16-year-old -- was found and identified the 12-year-old as the one who shot Trent.
