Hudson County prosecutors say a woman attending a vigil for a man killed in a Jersey City shooting was fatally shot herself when someone opened fire on the crowd.

Prosecutors say the shooting occurred Tuesday shortly before 1 a.m.

Felicia Stewart, a 30-year-old city resident, was hit in the back and was taken to a hospital, where she was pronounced dead a short time later.

It wasn’t immediately clear what sparked the gunfire or if more than one shooter was involved, but no other injuries were reported.

No arrests have been made.
