Mabel Castillo, a 25-year-old Latina, was shot to death on January 7, 2017, in Boyle Heights, Los Angeles. The shooting happened in the 600 block of South Evergreen Avenue after Castillo, her 4-year-old daughter and Castillo’s boyfriend went to her ex-boyfriend’s apartment to discuss custody. An argument inside the apartment preceded the violence. As Castillo and her daughter were leaving, the ex-boyfriend, identified as 30-year-old Jonathan Andrew Arteaga, came out with a gun, chased them and fired several shots. Castillo was struck in the chest and later died at hospital at 5:50 p.m.; her boyfriend suffered a gunshot wound to the arm and the child was unharmed.

Arteaga was arrested on January 11, 2017, in the Van Nuys area and was charged by the Los Angeles County District Attorney with murder, assault with a semiautomatic weapon and child abuse. The Los Angeles Police Department investigated the crime and asked the public to provide information to Detective Jose Ramirez or Crime Stoppers.
