PITTSBURGH — A man convicted of fatally stabbing a Pittsburgh police dog has been sentenced to an additional 1 to 3 years for probation violations in two other cases.

A judge Tuesday ordered 23-year-old John Rush to serve the time after he completes a sentence of 17 to 44 years for torture of a police animal and other charges.

Prosecutors said the Stowe Township man was on probation after pleading guilty in assault and statutory sexual assault cases when he stabbed K-9 unit dog Rocco in January 2014.
