Joseph Chang Ha, 67, was shot and killed on February 27, 2009, in Philadelphia’s Olney neighborhood, near the 400 block of West Chew Avenue. He closed his business at about 6:30 p.m. that Friday and was later found beside his car; his pockets were turned inside out, a detail that prompted suggestions robbery may have been involved though no motive was confirmed.

Merchants recalled Ha had been in a loud dispute with a customer in the days before the killing and that police had been called to his business on similar incidents. Neighbors and fellow business owners expressed shock and fear, worrying Asian proprietors might be targeted. The 5th and Olney Business Association offered a $2,600 reward for information leading to an arrest and conviction, and police asked anyone with knowledge of what happened outside Ha’s business that night to come forward.

Does anyone remember seeing activity near the 400 block of West Chew Avenue on the evening of February 27, 2009, or know more about disputes involving Ha in the days before he was killed?
