The state attorney's office filed second-degree murder charges Friday against a man who claimed self-defense in a deadly Tampa dog park shooting. Officials called him the "aggressor." The state also is seeking an enhancement as a hate crime against 65-year-old Gerald Radford, the Office of the State Attorney said in a news release. Loved ones of 52-year-old John Walter Lay, who went by "Walt," said Radford targeted him for being gay. Hillsborough County Sheriff's Office deputies arrested Radford early Friday afternoon. Radford called 911 during the morning of Feb. 2 and told dispatchers he shot a man at West Dog Park on North Occident Street. He said he and Lay were in a "scuffle" when he pulled out his gun and shot him. There reportedly were no witnesses to the shooting.
