Murder in California City, CA.

California City has too many unsolved murders and missing. The murder of 23 year-old, Deverrie Schiller is still unsolved. She left her mother's home on the 25th of June 2016 and was found, dead, by 5 young boys, in Cal City's Central Park. The "friend" she was last scene with wasn't interviewed until 7 months after her murder. The only way he was interviewed was because Deverrie's mother, Deb, called the detective and told him the family was packing a U-Haul and ready to leave the state. The police let him leave the state and there have been no arrests or persons-of-interest. Listen to the events of the 25th and 26th. Tell me WHY this is a cold case!?
