The search for a missing 5-year-old boy was relaunched at Cachuma Lake on Saturday morning.
The Santa Barbara County Sheriff's Office joined several Southern California law enforcement agencies at 7 a.m. and provided 15 members of the Sheriff's Search and Rescue Team and four search dogs, along with eight deputy members and horses from the Mounted Enforcement Unit.
Aramazd Andressian Jr. was reported missing by his mother on April 22 after his father failed to drop him off in San Marino.
That same morning, the missing child's father, who had custody of his son, was reportedly located unconscious at Arroyo Park in South Pasadena. However, his young son was nowhere to be found.
The boy was reportedly last seen at Disneyland with his father on April 20.
Aramazd Andressian Sr. was originally arrested on suspicion of child abduction but was later released. Investigators said that he was not cooperative, and claimed not to remember what happened to the boy.
Authorities decided not to forward the case to the Los Angeles County District Attorney's Office for review.
The South Pasadena Police Department launched an investigation to locate the missing child, and on April 23 the Los Angeles County Sheriff's Department Homicide Bureau was requested to help.
During their investigation, detectives learned Andressian Sr. spent April 21 visiting Lake Cachuma Recreation Area. Detectives also recovered evidence that led them to believe that the boy's father also traveled around the area to Solvang and Nojoqui Falls.
After three days of attempting to locate the boy at Cachuma Lake, authorities halted their search April 25.
Participating in Saturday's search were the Los Angeles County Sheriff's Department Homicide Bureau, County Sheriff's Office, Los Angeles County Fire Department, South Pasadena Police Department and partner agencies throughout San Gabriel Valley and the local team.
The boy is 3 feet, 5 inches tall and weighs about 55 pounds. He has short brown hair and brown eyes.
Investigators are asking anyone with information about the boy to contact the Los Angeles County Sheriff's Homicide Bureau at 323-890-5500.
