Detectives used cadaver dogs to search the sprawling wilderness off the side of the 60 Freeway in Moreno Valley. They had the boy's father, Jake Haro, with them as they searched.

Authorities are searching for the body of 7-month-old Emmanuel Haro, who went missing on August 14. His parents, Jake and Rebecca Haro, were arrested on murder charges following contradictory statements made by Rebecca regarding the child's disappearance.

The search on Sunday did not lead to the baby. Jake Haro and his wife Rebecca, the parents, were arrested on suspicion of murder on Friday.
