AMITY — Two men and a boy were found fatally stabbed in a home in remote northern Maine, putting townspeople on edge as police hunted for someone who apparently took off in a pickup truck belonging to one of the victims, authorities said today.

Police identified the victims as 55-year-old Jeffrey Ryan and his 10-year-old son, Jesse, who lived in the home, as well as 30-year-old Jason Dehahn, a friend who also lived in Amity. Police said the bodies were discovered by a relative at about 9:30 p.m. Wednesday in a mobile home on U.S. Route 1, 15 miles south of Houlton.

Police are looking for Ryan’s 1989 Ford F-150 pickup truck with Maine registration 4155 RY. The driver of the pickup “is a person of interest and should be considered dangerous,” said State Police spokesman Steve McCausland.

The deaths sent shock waves through Amity, a farming and logging community about 200 miles northeast of Portland. Residents are wondering what really happened in the tidy mobile home with a tree house and an above-ground pool in the front yard.

“Somebody has to be pretty cold to stab a kid,” Amity resident Larry Hamilton said. “That’s what bothers everybody so much, that there was a kid involved.”

State police detectives were gathering evidence and interviewing relatives and friends, police said. The bodies were expected to be taken to the Medical Examiner’s Office in Augusta for an autopsy today.

Three people were stabbed to death near Houlton Wednesday night, Maine State Police said this morning.

The victims were two men and a young boy, said police spokesman Stephen McCausland. He did not release their names, saying their relatives were still being notified.

The homicide happened at a home along Route 1 in Amity, which is about 15 miles south of Houlton.

McCausland said police are looking for a 1989 Ford F-150 pickup truck taken from one of the victims. It is blue and silver with Maine license plate 4155 RY.  McCausland said the truck has running lights on the top of its cab, and white front wheels and silver wheels in back.

Anyone who sees the truck is asked to call 911 or State Police at 624-7076.

One of the victim’s relatives discovered the bodies around 9:30 p.m. Wednesday, McCausland said. The bodies are being taken to Augusta for an autopsy today.
