VALRICO — Minutes before David Rex stabbed his friend, they were drinking iced tea in the front yard.
Alan Caise doesn't know why Rex did it, as deputies say he did. They had been friends for years.
Rex went over to Caise's Valrico house at about 2 p.m. Wednesday. Shortly after Rex arrived, he said he was hungry. Caise gave Rex some food.
After a bit, Rex walked over to the side of the house. When he returned, deputies say, he stabbed Caise in the chest and back.
Rex ran away.
Deputies soon arrested Rex at his Valrico home on charges of aggravated battery and for being a felon in possession of a firearm.
Caise was taken to Tampa General Hospital. He was released Thursday afternoon.
While waiting for a ride home from the hospital, Caise told a reporter he did not know why his friend stabbed him.
They weren't fighting. Maybe Rex had been drinking, Caise said, adding that Rex has a "chemical imbalance."
Hillsborough deputies are confused about Rex's motive — if he had one at all.
"I'm baffled, too," Caise said. "We were just having iced tea. We weren't arguing."
