It happened on the jitney March 5th just after midnight at Summit and Pavonia Avenues in Journal Square.
The 48-year-old victim, an Ecuadorian immigrant, says the lone passenger on his bus robbed him, and then shot him in the back as he tried to escape.
The suspect ran over the victim's legs as he took off in the mini-bus.
The suspect is described as an Hispanic male, 18 to 25 years old, 150 to 180 pounds, with an average build.
A $4,000 reward is being offered for any information about the crime.
Anyone with information is asked to call Jersey City Police at 201-547-5246.
