PLAINFIELD, N.J. (AP) — A motorist accused of causing a hit-and-run crash that led to a pedestrian's death is now charged with death by auto.

Union County prosecutors say Dominic Gomez also faces a count of leaving the scene of a fatal accident stemming from the June 7 crash in Plainfield.

Authorities say the 23-year-old Plainfield man ran a stop sign and collided with another vehicle. They say Gomez's car then struck and killed 37-year-old Plainfield resident Antonio Marquez-Melgar before Gomez drove off.

Gomez remains jailed pending his initial court appearance. He could face up to 20 years in prison if convicted on both counts.

It wasn't known Thursday if Gomez has retained an attorney.
