(WPXI) – The Penn Hills community is remembering a beloved social studies teacher, father and mentor who was killed in a crash along the Parkway East on Friday. Josh Willy worked at the Penn Hills school district for 23 years. High School junior Chase Delehanty, 17, said his social studies teacher had a way with coworkers and parents, but especially with his students. State police are still investigating the crash. Willy died Friday morning after police said he veered off the Parkway East just past the Squirrel Hill Tunnel and went over a guardrail. His car plunged more than 80 feet into the ravine below.
