Ismael 'Tristan' Santisteban, who is autistic, disappeared from a home at 7719 Hatteras Drive.
Law enforcement issued an Amber Alert for him about 8 p.m. Thursday, sending the search effort statewide.
Deputies initially reported that Ismael was with Adam Matos, 28, of Hudson, and sent out a description of his 1991 Ford pickup truck. But late Thursday, Sheriff Chris Nocco said deputies had found Matos’ truck because it had been towed from the area a few days ago.
Matos may have left Ismael with someone else, Nocco said, because Matos has been seen in the area by himself recently.
Ismael’s relationship to Matos is unclear, Nocco said, but he may have considered himself a father figure to the child.
The autistic boy is likely not receiving the care he needs, Nocco said.
"He's probably petrified," Nocco said. "I beg of you. If you have any sense of morality, if you have any sympathy, look at that little boy and know that he's scared to death."
Deputies were called to the home Aug. 28 for a domestic incident, Nocco said, and the boy was seen there at that time. The boy's mother told deputies that Matos held a knife to her throat.
They were called to the house again 10 a.m. Thursday for a welfare check. A relative of the family in Pennsylvania called deputies to say the family had not been heard from since last week.
During the check, deputies found evidence of “grave alarm” that caused them to search the surrounding area, Nocco said.
The bodies were found piled on top of each other near a mine about ¾ of a mile away. Nocco has not said how the dead may have been related to Ismael.
Deputies were searching bars and homeless camps Thursday for Matos. They will perform a “grid search” Friday of woods in the area of the home.
"There has been a lot of activity in and out of the driveway," neighbor Ed Nilon said. "The motor home showed up eight to 10 days ago and has not moved."
Matos and Ismael moved to the Hudson home in July from Orefield, Pa., with at least four others. According to Nocco, Matos had several run-ins with the Pennsylvania police. His criminal history includes prior arrests for assault, harassment and theft.
Approximately two weeks ago, Matos showed up to the Get Hooked Grill in Hudson looking for a job.
"We were looking for a dishwasher so I threw him in the dish pit," restaurant owner John Hill said. "He was a clean cut, nice looking young man. He came in, did his job, didn't say much, and went home."
However, about a week into his employment there Hill said he received a strange phone call from Matos saying he could not come in to work due to a family emergency. This was on Aug. 27. The next day, deputies said the domestic incident took place.
Jacob Torres, a cook at the restaurant, said he last spoke with Matos when he came by the restaurant to pick up his last check on Aug. 29. He said he appeared normal. He recalls him mentioning getting a new job fishing with a neighbor.
"I'm really surprised. Really surprised," said Torres. "He was a really quiet guy."
Matos is considered armed and dangerous.
