SCOTT TOWNSHIP, Pa. — (WPXI) – Bagpipers played a moving tribute during a final salute at a viewing for fallen Pittsburgh Battalion Fire Chief John Walsh. Family, friends and fellow firefighters showed up in the hundreds throughout the day at William Slater Funeral Home in Scott Township Sunday to pay their respects to the beloved firefighter and family man who died in the line of duty earlier this week. The 60-year-old battalion chief collapsed while commanding the scene of a house fire in East Hills Wednesday. Walsh later died at the hospital. His family believes he suffered a heart attack. The firefighter served the department for 37 years. Walsh’s SUV with Station 8 was parked outside the funeral home draped in a black ribbon in honor of the fallen battalion chief. Two firefighters stood watch over the battalion chief’s body overnight until his funeral procession Monday morning, which went from the funeral home to St. Paul Cathedral in Oakland.
