Pittsburghers, many of them pet owners, took to social media with heavy hearts following the death of Pittsburgh police dog Rocco Thursday evening.
Authorities say 8-year-old Rocco was injured Tuesday night when police arrested a man on warrants for probation violations and failing to register as a sex offender.
Twenty-one-year-old John Lewis Rush was one of Allegheny County's most wanted fugitives. Police say he stabbed Rocco in the back and wounded two officers before being taken into custody.
Mayor Bill Peduto said Rocco served the city faithfully and "paid the ultimate price in the line of duty."
