Kidnapping suspects believed to be outside California

GORMAN, Calif. -- Two people suspected of kidnapping a murder victim's three children have likely fled California, officials said.

Los Angeles County sheriff's officials believe Joshua Aaron Robertson, 27, and Brittany Humphrey, 22, traveled on Interstate 40 and passed through Arizona and New Mexico. But that's when their trail goes cold.

Investigators said Robertson and Humphrey have family connections in several states, including Nebraska, Kansas, Louisiana and Mississippi.

An arrest warrant has been issued for both Robertson and Humphrey, who are suspects in the kidnapping of three children, as well as persons of interest in the murder of Kimberly Harvill, the kids' mother.

Sheriff's officials say Robertson and Humphrey allegedly kidnapped Joslynn Watkins, 2; Brayden Watkins, 3; and Rylee Watkins, 5 either before or after Harvill's death. Harvill is Humphrey's sister.

"The children are at risk. We consider them at risk, and that's why we reached out to law enforcement in all those states, and they're working hand-in-hand with our investigators and trying to locate the children," said LASD Lt. Joe Mendoza.

Sheriff's officials told Eyewitness News that in addition to Harvill's three kidnapped children, the two suspects may also be traveling with Robertson's infant child.

Harvill's body was found Aug. 14 by a motorist who had made a rest stop on Gorman Post Road, just north of the 138 Freeway, in the northwest area of the county.

Investigators believe Robertson and Humphrey are traveling in Harvill's green 1999 Ford Expedition, which may have the California license plate 7BEK024, though authorities believe the plate may have since been replaced.

Robertson has a criminal history - he was previously arrested for possession of a firearm. Officials describe him as armed and dangerous.

Humphrey is described as white, 5 feet 2 inches tall, weighing 120 pounds, with blond hair and blue eyes. Robertson is described as white, 6 feet 2 inches tall, weighing 170 pounds, with blond hair, blue eyes and tattoos on his right arm.

Anyone who sees the children or the suspects is asked to call local law enforcement by using 911, or Sgt. Ken Perry or Detective Scott Matlock of the Los Angeles County Sheriff's Department at (323) 890-5500. Those who wish to remain anonymous may call Crime Stoppers at (800) 222-8477.
