Earlier Tuesday night, police received a report of a hit-and-run crash involving Timothy Harris in East Marlborough Township. He then fled that scene and crashed again in Kennett Township just before 10 p.m. After he crashed, police say Timothy Harris exited his vehicle, shot himself and died by suicide.

One of Harris’ sons attended Lincoln University, where a spokesperson for the school says the mother was an Aramark employee at the university.

“He was around here during the summer, winter, it didn’t matter the weather,” Briana Townsend, of Lincoln University, said. “He was always exercising, trying to lose weight.”

Law enforcement has been at the house all day. The Troop J Major Case Team has been activated to investigate the double homicide. They are working in conjunction with the Kennett Township Police Department, Chester County detectives and the Chester County District Attorney’s Office.

“I never thought I’d live somewhere where something like this could happen,” Townsend said. “You see it everywhere else, on the internet and then it happens around you and you’re like wow.”

This is still a very active investigation. Eyewitness News has been told that there’s currently no threat to the public.
