AMHERST, N.H. — Authorities awaited dental records Monday of a missing executive to see whether he was the pilot who crashed a plane into his house, killing himself and destroying the home, a newspaper reported.

After the crash and fire, little was left of the house but its foundation. It stood at the end of a winding driveway in a development of expensive homes.

Louis W. Joy III, 43, owned the house and lived there with his wife and their 8-year-old daughter. They recently moved to Amherst from Newark, Del.

Local police wouldn't comment about the investigation.

However, a source close to the investigation told The Union Leader of Manchester that authorities were waiting to receive Joy's dental records from Delaware.

Authorities say it would be at least Tuesday before they could identify the pilot's body.

No one on the ground was injured. Joy's wife, Jo, and daughter were away from home at the Saturday morning crash but joined investigators at the scene later in the day.

The wife and daughter couldn't be located for comment Monday by The Associated Press.

The single-engine plane was registered to Joy's company, Manufacturing Excellence Inc., based in Newark, Del. He had been president since 1987 and lectured on motivation and management. The company's Web site lists Fortune 500 companies as clients.

Neighbors said the aircraft did not appear to be in trouble before the 7:40 a.m. crash.

"I kept hearing a plane going around and around," said neighbor Marie Seroskie. "I thought he was buzzing someone. I saw him from the bedroom window and I waved at him and then the engine went completely dead."

The plane had taken off about 20 minutes earlier from Nashua Municipal Airport, 12 miles away, said Jim Peters, a Federal Aviation Administration spokesman. He said the pilot had filed an instrument flight plan with a destination of Atlantic City, N.J.

Joy's home in Delaware was bought last year by Wendy Hamme, who said neighbors considered him eccentric and a recluse. She said almost every window in the house had been nailed shut.

"Nobody knew too much about him. They all thought he was with the relocation program with the FBI or something Mafia-related. They all thought he was really strange," she said.

"He seemed like a charmer. But if he didn't get his way, he was nasty," she said.

Hamme said everything Joy installed in the house was the biggest and the best, including a garbage disposal "that could probably grind a car up."
