An off-duty Elizabeth police officer has pleaded guilty to vehicular homicide in a crash that killed a motorcyclist last fall.

According to the Middlesex County prosecutor's office, Romulo Meneses-Alvarez, 30, also pleaded guilty Monday to evidence-tampering and driving while intoxicated in the Oct. 31 crash.

Authorities said he was off duty and driving a Jeep Wrangler when he collided with the victim's motorcycle in Elizabeth, killing Jairo Lozano, 29.

A plea agreement with prosecutors calls for a term of 364 days in the county jail when the defendant is sentenced July 13.

He must also forfeit his current public employment with the Elizabeth Police Department.

Middlesex County prosecutors have been handling the case because Union County prosecutors have an unspecified conflict.
