Three people were found dead of apparent gunshot wounds Sunday night at a home at 1227 Highland St., according to Pekin police Chief Greg Nelson.
Officers were called to the address at about 9 p.m. and began an investigation that Nelson said could involve a murder-suicide scenario.
Neighbors identified the residents of the home as 77-year-old Ira Lee Clemons, his 75-year-old wife, Barbara, and their 52-year-old son, Allen Scott Clemons.
Officials declined to provide the names of the deceased, pending notification of family members.
The couple's bodies were found in a bedroom, while the son was found downstairs, according to Pekin Police Public Information Officer Don Jolly.
"We're not looking for a suspect," he said.
Jolly said the call was in response to a well-being check from a relative. It is unknown when the deaths occurred.
Neighbor Nate Walker of 1223 Highland said the man who lived at the address, whom he identified as Lee, was a good neighbor.
"He gave us tomatoes — nice guy," he said. He added there were a lot of police calls to that address.
Walker also said he thought he heard a knock on the door between 8:45 and 9 p.m. He wasn't sure if it was his home or the neighbor's, but 15 minutes later he heard sirens.
Jolly said most of the police calls were Emergency Response Service calls. "I think the parents were concerned about the son's behavior," he said.
