BELVIDERE, Ill. (AP) — A 24-year-old man arrested for a parole violation was identified Wednesday as a person of interest in the weekend slayings of a man and two young sons in northern Illinois.

The Huntley man had spent part of Sunday with Andrew Hintt, 31, and the boys, Benjamin, 7, and Sebastian, 5, the Belvidere police department said.

The man was interviewed by police and was being held at the Boone County jail. Separately, police seized evidence from a house in Huntley.

The bodies of Hintt and the boys were found at Hintt’s Belvidere home Sunday night. Belvidere is about 70 miles (110 kilometers) northwest of Chicago.

More than 50 people gathered outside the home Tuesday night to pray.

“I can’t tell you it’s not going to hurt. It’s going to hurt for a while,” the Rev. David Smith of First Assembly of God Church told the family. “But look around and remember: In the moment that it hurt the most, these people came out here to be beside you.”

Hintt’s aunt, Theresa Eileen, said he operated his own meat truck.

“He spoiled the heck out of his kids,” Eileen told the Rockford Register Star. “He would take them everywhere. He brought the boys their own (electric) dirt bikes. He taught them how to ride.”

Hintt and his fiancee were the parents of five children, though Benjamin and Sebastian lived with other relatives in the area. Eileen said Hintt regularly saw them.
