Sierra Elizabeth Castilleja-Riemer, 22, of Bakersfield was found with gunshot wounds in the 1700 block of Custer Avenue on January 10, 2021. She was taken to Kern Medical but died of her injuries; a second victim, 24-year-old Ramon Rodriguez Muro, also died at the hospital. The Kern County Sheriff’s Office identified Sierra and asked anyone with information to contact the Bakersfield Police Department.

Police have not released information about a motive. Sierra’s family launched a GoFundMe to help cover funeral costs and support her four children. Court filings show she had faced two felony counts of willful cruelty to a child that were dismissed shortly before her death, but officials have not linked those dismissed charges to the shooting.

Who in Bakersfield might have seen activity around Custer Avenue that night or has information about Sierra’s final movements?
