The couple was charged with murder and kidnapping in September after the body of Humphrey's stepsister, 26-year-old Kimberly Harvill, was found in northern Los Angeles County, in brush along Gorman Post Road. The sheriff's department said the victim had been shot in the upper body.
After killing Harvill, Humphrey and Robertson kidnapped her three young children and fled to Colorado. The children were found safe in a motel outside Albuquerque, New Mexico, about 10 days later.
Humphrey and Robertson were arrested a day after the children were found. Robertson is also charged with a count of possession of a firearm by a felon.
