James Dungy, the 18-year-old son of Indianapolis Colts coach Tony Dungy, was found dead in a Tampa-area apartment, police said Thursday. No foul play is suspected, but a cause of death won't be announced pending an autopsy, said Vida Morgan, a secretary in the Hillsborough County sheriff's office. James Dungy's girlfriend found him when she returned to the Campus Lodge Apartments in Lutz, Fla., the sheriff's office said in a news release on its Web site. Police responded at 1:32 a.m. Thursday and performed CPR on Dungy before he was taken to University Community Hospital, where he was pronounced dead. Tony Dungy has left the Colts and is in Tampa. The Colts (13-1) are at Seattle on Saturday, and team president Bill Polian said that assistant head coach Jim Caldwell has taken over for Dungy.
