Officials on Friday announced a $20,000 reward for information leading to the arrests of a man and woman wanted in connection with a homicide in Carson as an Amber Alert remains in effect for a missing teenager believed to be with the pair.

Maricela Mercado, 40, and her ex-husband Roman Cerratos, 39, have been identified as suspects in the fatal shooting of 32-year-old Jeffrey Appel, according to the Los Angeles County Sheriff’s Department.

Appel, of Las Vegas, was found dead inside a car that was parked in a lot in the 400 block of East Carson Plaza Drive on April 16. He died from gunshot wounds to the neck and torso, and his death was ruled a homicide, according to the autopsy.

Mercado’s daughter, 15-year-old Alora Benitez, was last seen with the two suspects in Torrance on April 17. CHP issued an Amber Alert for the missing teen the following day.

A BMW associated with the alert was found unoccupied in the border town of San Ysidro on April 19.

The $20,000 reward, offered jointly by the L.A. County Board of Supervisors and the City of Carson, is for information that leads to the suspects being arrested and convicted, according to a sheriff’s bulletin.

Cerratos and Mercado should be considered “armed and dangerous,” the bulletin stated.
