Anthony Turra, a 61-year-old Italian-American from Philadelphia, was shot dead on March 18, 1998 while leaving his home to go to the federal courthouse. Turra, who used a wheelchair and suffered from cancer, emphysema and congestive heart failure, was struck twice by a gunman wearing a black ski mask. Police described the slaying as an organized crime assassination.

Turra was a reputed member of the 10th & Oregon Crew, a South Philadelphia gang. He and his son, Louis Turra, were among those indicted on charges including drug trafficking, racketeering and conspiracy to commit murder; jurors were deliberating those counts when Turra was killed. Authorities questioned two mob figures in connection with the shooting but did not identify suspects, and the defense request for a mistrial was denied with the judge saying any verdict against Turra would be sealed.

Who in the neighborhood or the courthouse area that day might have seen the masked shooter or unusual activity?
