TAMPA, Fla. - The son of Indianapolis Colts coach Tony Dungy used a belt to hang himself from a ceiling fan, according to the 911 call the teen's girlfriend made when she found him last month.

Antoinette Anderson returned to James Dungy's apartment after a 10-minute walk early Dec. 22 to find him apparently lifeless, according to tapes released Wednesday. The tape is the first public indication how James Dungy, 18, killed himself.

"I think my boyfriend's dead," an anguished Anderson told an emergency dispatcher. "I think he tried to hang himself or something."

She told the dispatcher she had used a knife to cut James Dungy down and that his roommate was asleep in another room.

"Get the roommate up," the dispatcher told Anderson. "You're gonna need some help here, OK?"

Anderson is then heard telling the roommate, whose name has not been released, "I think he's dead, like for real. And I'm on the phone with 911."

The two tell the dispatcher Dungy isn't moving. The dispatcher tells them how to perform CPR as Anderson cried.

"Force two deep breaths of air into the lungs just like you're blowing up a big balloon," the dispatcher said.

"Did you do that?"

"Yes," Anderson said. "I just don't think he's alive."

"Did you feel air going in?" the dispatcher asked.

Anderson replied, "No. No."

A Hillsborough County sheriff's deputy soon arrived and took over the CPR. A paramedic crew took Dungy to a hospital, where he was pronounced dead.

The local medical examiner has called the death an apparent suicide, but has refused to give an exact cause pending results of toxicological tests that should be ready in about a month.

On Oct. 21, James Dungy was treated after overdosing on painkillers. Then, he calmly told a 911 dispatcher he "was just being stupid" and had taken about 18 pills. He was taken to a hospital for treatment.

James Dungy had moved back to the Tampa area from Indianapolis last year to attend college. His father had coached the Tampa Bay Buccaneers from 1996 to 2001.

Tony Dungy missed one game after his son's death, returning to the Colts' sideline last Sunday. The Colts, the top seed in the AFC, open the playoffs Jan. 15 in Indianapolis.
