PITTSBURGH (AP) — Prosecutors have announced plans to seek the death penalty in the slaying of an off-duty Pittsburgh police officer shot to death in a street confrontation last month. The Allegheny County district attorney’s office informed the court Monday of intent to seek capital punishment should 30-year-old Christian Bey be convicted of first-degree murder. Prosecutors also unsealed the homicide and firearms crimes criminal complaint against Bey in the July 14 shooting of 36-year-old Officer Calvin Hall.
