Rachel Castillo was reported missing after her sister found a bloody scene in her home on November 10. The discovery sparked a search for the 25-year-old woman, whose mobile phone, car keys and vehicle were still at the home she shared with her sister Emily. On Sunday, Simi Valley detectives say they found human remains in a remote Antelope Valley location. The medical examiner identified the remains as Rachel Castillo. Detectives arrested Rachel Castillo’s ex-husband, Zarbab Ali, a 25-year-old Hawthorne resident. He was arrested at his parents’ home in Victorville “in connection with Rachel’s murder.” Family members and friends held a vigil early Sunday night to honor Rachel and ask for the public’s help in the then-missing-person case. It seems that at that time they were not aware of the new developments in the case. Police have not released further details.
