Authorities in Pennsylvania released the identities of the three bodies that were found dead on Thursday evening.
The coroner's office identified Schlenoff's father as 71-year-old David Schlenoff, and his mother as 66-year-old Elizabeth Schlenoff.
According to the release, all three died from a gunshot wound to the head.
"There was no fire," Boyer told the outlet. "It was just a pot of food burning on the stove."
Boyer added that he met with responding officers shortly after entering the house.
"I was met by a police officer, who told me to step back, that it was a police incident," Boyer told The York Dispatch. "The Southern Regional Police Department discovered the bodies."
Coroner Pam Gay said in a news release Friday that Schlenoff's death is listed as a suicide while his father and mother's deaths are listed as homicides. The next of kin have been notified and there will be no autopsy.
Officers with the Southern Regional Police Department are continuing to work on the investigation.
New Freedom Borough is located in the southern portion of York County in Pennsylvania, about 61 miles from Washington.
