A California woman, wanted by authorities in connection with a deadly shooting in April, was found in Mexico on Tuesday with her 16-year-old daughter, and the pair have been deported to the United States, the Los Angeles County Sheriff’s Department said.

Marcela Mercado, 40, and Alora Benitez, her daughter – whose disappearance in April triggered an Amber Alert -- were arrested by authorities in Chihuahua, Mexico, and deported for entering the country illegally, the Sheriff’s Department said Wednesday.

Mexican authorities handed the two to Customs and Border Protection (CBP) agents in El Paso, Texas, KTLA reported. El Paso authorities arrested Mercado in accordance with a warrant from Los Angeles County, the station said.

Mercado remains in custody until her extradition to California. Her daughter is in FBI custody until she can be reunited with other relatives, the Sheriff’s Department said.

Mercado and her ex-husband, Roman Cerratos, 39, are suspects in the fatal shooting of Jeffrey Appel, 32, a Las Vegas man, authorities said. On April 16, Appel was found with gunshot wounds in a car in Carson, 13 miles south of downtown Los Angeles.
