On the evening of December 22, 2015, 36-year-old Abner Dominguez of Jersey City was found on the ground beside his running vehicle near 93 Roseville Avenue in Newark with a gunshot wound. He was taken to University Hospital and pronounced dead at 10:56 p.m.

Dominguez was a father of two sons, Jean-Batiste Nathaniel and Jean-Paul Gabriel, and worked as a DJ in Jersey City. The Essex County Prosecutor’s Office Homicide/Major Crimes Task Force and the Newark Police Department opened the investigation; the motive was not immediately clear and no suspect had been identified at that time.

What can anyone who knew Abner or who was in the Roseville Avenue area that night add to the timeline?
