Michael Strong was 21 when he was shot and killed in Philadelphia on January 7, 2017. Known in his neighborhood for generosity and for helping elderly neighbors, he had been shoveling snow that day and refused payment. After returning home, he went back outside and was shot and later died at Temple University Hospital.

No arrests have been announced and the Philadelphia Police Department lists the case as unsolved. Michael’s mother, Sylvia Murray, has spoken about her grief and regret. His high school, Simon Gratz Mastery Charter School, honored him with a memorial banner; friends and teachers remember him as caring and kind.

Who in the community might have seen Michael that afternoon or have information about what happened after he went back outside?
