Pittsburgh police led the body of a fallen officer from the hospital to the medical examiner’s office Wednesday.
Officer Calvin Hall died three days after being shot.
He was off duty at the time of the incident Sunday morning — when a disagreement during a party spilled in a street.
The 36-year-old was shot in the back three times.
The investigation has now shifted into a homicide case.
No arrests have been made, but people at the party have been questioned.
