DC police have since confirmed that the victim - a Peace Corps executive - was killed by a stray bullet.
Initially, his wife thought she heard firecrackers, according to the family member.
Then she saw him lying on the ground.
Police began investigating after they responded to a reported shooting in the 1400 block of R Street, Northwest around 9:11 p.m.
When they arrived, they found 53-year-old Jeremy Black suffering from gunshot wounds.
Black was taken to a local hospital, where he died.
The night of the shooting, people who had been eating at the restaurant told FOX 5 they heard gunfire but didn’t see anything.
Police have identified a vehicle they believe is linked to the crime, and released a surveillance image showing it.
Police are offering $25,000 for information that leads to the arrest or conviction of the person or persons responsible for Black’s death.
