She was reported missing Thursday night after her sister returned to the apartment they shared in the Wood Ranch neighborhood and found a large amount of blood - that investigators said was consistent with a, "serious injury."
Late Sunday Simi Valley Police said Castillo's remains had been found in a remote area of the Antelope Valley and were positively identified with the assistance of the Los Angeles County Coroner.

"The primary suspect in this case is Rachel's ex-husband, 25-year-old Hawthorne resident Zarbab Ali," Police said in a statement.
It was believed that Ali had picked up the couple’s two sons from Castillo 's apartment the day the young mother went missing.
"Mr. Ali was arrested this afternoon at his parents' home in Victorville in connection to Rachel's homicide," the statement said.
Castillo's father Christopher, a retired federal law enforcement agent, drove in from Northern California Friday to assist with the search for his daughter.
"She is in need of immediate help," he told NBC4 Friday night, begging for anyone with information on her disappearance to call police.
"Just think if this was your kid," he said.
Neighbors say they didn’t hear or see anything out of the ordinary on that day.
“Stuff like this doesn’t happen here…heartbreaking,” Frank Avila, a neighbor, said.
Ali lives in Hawthorne but police arrested him at his parents home in Victorville.
Castillo and her sisters were very much involved in their church. Members of St. Rose of Lima Catholic Church organized a prayer vigil for Castillo before they heard the news of her death.
Friends who prayed and hoped for a different outcome are now trying to cope with a devastating loss.
