According to police, a shooter opened fire on a car, killing Wopo and injuring another passenger.
The up-and-coming hip-hop musician, whose real name was Travon Smart, previously revealed that he had been shot twice in the past.
Wopo's lawyer, Owen Seman, told the Associated Press that he had spoken to his client to discuss a major record deal just minutes before he was shot dead.

RIP Jimmy Wopo, for my money the best rapper to ever break out of Pittsburgh.— Otto Von Biz Markie (@Passionweiss) June 18, 2018
Radiant 1000-watt charisma and a legitimately original stylist. Kendrick's "Humble" was nothing if not an homage to "Elm Street."
This is just terrible and senseless. pic.twitter.com/KgKcEhTVMa
