Ali faces multiple special allegations, including the use of a deadly weapon, murder for financial gain, and murder by lying in wait. He is also charged with unlawful mutilation, disinterment, or sexual contact with a human corpse.

The backstory:

Rachel Castillo, 25, was last seen on Nov. 10. Earlier that day, Castillo had dropped off her two children with her ex-husband. When her sister, who lives with her, arrived at their apartment on East Country Drive, she found a large amount of blood inside. Castillo's phone and keys were there, as well as her car in its usual spot.

Her body was found three days later in a remote area of the Antelope Valley. Ali was arrested at his parents' home in Victorville the same day.
