Allegheny County Police say officers found the suspect dead with a single gunshot wound to the head. They say it’s believed to be self-inflicted.

His 65-year-old father and 59-year-old mother were found dead in the home on Gilkeson Road.

Christian Dryden, who lives next door, said the 59-year-old mother would always bake treats for the Greek Festival at the church down the street.

“You don’t expect it to happen that close and not in Mt. Lebanon, it’s just shocking,” said Dryden.

“None of us remember them having any fights or harsh words and neither the son, that’s why this was so weird. He was hard-working, did a lot of car work, yard work, gardening and took care of his dad,” Dryden added.

Police have said they are familiar with the suspect, a 25-year-old male, saying they’ve been to his home in the past.
