ST. JOHNS COUNTY, Fla. -- Authorities in Florida launched an investigation into what they called one of the strangest accidents they've ever seen.

Woman Finds Boyfriend Dead In Cat Door

Investigators said 32-year-old Charles Tucker Jr. was using the cat door early Saturday morning as a way to get back into his girlfriend's St. Augustine home after she kicked him out.

Deputies said several hours after Tucker's girlfriend told him to leave she found him stuck in the cat door.

"Maybe at 3 a.m., my older brother called me and told me -- he was crying -- that she had called him and she found him dead in the door," said Tucker's friend, Will Elliot.

Elliot lives down the street from the home where Tucker was found dead.

"He's a big guy. I don't even know how he could fit through there," Elliot said. "Probably to get in and unlock the door. They said he had one arm through there and his head was caught in there like he was to reach up and unlock the door because there's no way he could fit through there."

Tucker's girlfriend called 911 when she found the 32-year-old stuck, but when officers showed up four minutes later -- he was already dead.

Officers said it was not the first encounter they had with Tucker that weekend. They said on Friday they found him slumped over the wheel of his car; He was taken to Flagler Hospital, and later released.

The cause of Tucker's death has not been released. Officers were awaiting autopsy results before releasing that information.

The door in which Tucker got stuck had been removed and put out with the trash Monday.

"Maybe he just passed out because there was no sign of struggle or anything. She would have heard him. She was in the house," Elliot said.
