A "mentally challenged" man found sobbing outside a house early Thursday was in custody after four people, believed to be members of his adoptive family, were discovered shot to death, police said.
"He said, 'What have I done? I killed them. They're going to put me away for a long time,' " said Raymond Neal, who owns the property.
The 21-year-old man, whose name was not released, was found sobbing and kneeling in the tall grass behind the house when police responded to a burglar alarm.
The victims found inside were identified as Larry Prink, 49; his wife, Barbara, 48; their adopted daughter, Heidi McCarthy, 41; and Barbara Prink's mother, Dorothy Lynch, 79.
The suspect was believed to be the Prinks' adopted son, Police Lt. Richard True said. The man was not charged but was being held as police gathered evidence.
He declined to elaborate on his description of the suspect as "mentally challenged" or discuss a motive.
