PITTSBURGH — Authorities say a man wanted in a drive-by shooting outside a western Pennsylvania bar that killed a man and injured two women last month has been arrested in Louisiana.

Allegheny County police said Sunday that 21-year-old Joshua Wardlaw was stopped by police in Louisiana for a traffic violation on Friday evening and taken into custody.

Lt. Andrew Schurman said he was identified and arrested on the Pennsylvania homicide warrant and is lodged in the Lafayette Parish correctional center awaiting extradition.

Police had been seeking Wardlaw in the Aug. 6 shooting outside Saloon 136 in Monongahela that killed 27-year-old Jonathan Minnie of Belle Vernon and injured two 27-year-old women.
