A search warrant was served at a Montebello home Thursday in connection with the investigation into the disappearance of a 5-year-old South Pasadena boy, sheriff's officials said.
More than a month after Aramazd Andressian Jr. was reported missing, sheriff's homicide investigators served the warrant at the home of Andressian's paternal grandmother in the 500 block of North Via Val Verde, the Los Angeles County Sheriff's Department said.
Several items were collected as evidence, sheriff's officials said, though they did not specify what those items were.
Aerial images showed two women — the boy's grandmother and aunt — being taken from the home to the East Los Angeles Sheriff's Station in a patrol car. They were later released.
The grandmother had been with her son, Andressian's father, and her grandson at Disneyland on April 20, the Thursday before the child's disappearance. That was the last confirmed sighting of the boy, authorities have said.
The boy's father, Aramazd Andressian Sr., allegedly told investigators he had taken medication that was not prescribed to him on April 22, the day he and his son went to Arroyo Seco Park in South Pasadena before a custody exchange, sheriff's Lt. Joe Mendoza said.
The father and son arrived waiting for the golf course to open, Mendoza said. The boy's father was later discovered unconscious at the park and the boy was nowhere to be found. He was reported missing that day.
The father was arrested and released from jail three days later.
Investigators revealed last week that the car the father and son were traveling in was found with "gasoline in the interior and doused all over the exterior." There were also matches, a gas container, and a rag that had been doused with gasoline found in the area near the vehicle's gas cap.
Andressian Jr.'s mother has organized numerous community canvassing events in many cities and is coordinating new searches this weekend. Volunteers will be distributing flyers starting 10 a.m. Saturday at the Ranch House in Ojai and at Mission Park in Ventura.
Anyone with information on Andressian's wherebaouts was asked to call sheriff’s homicide investigators at 323-890-5500 or anonymously at 800-222-8477.
A $20,000 reward has been offered by the Los Angeles County Board of Supervisors for information that helps find the child.
