The elder Andressian told investigators that he took his son to Cachuma Lake in Santa Barbara County - about 145 miles (233.34 kilometers) from Disneyland - the following day, but detectives found no evidence the boy had been there. Sheriff's officials revealed Wednesday the father took prescription pills and was found in a auto doused in gasoline.
"My son's disappearance is my worst nightmare", she said, adding that she thinks Aramazd is still alive.
"We are still remaining optimistic until we find out otherwise", Mendoza said.
Mendoza said a gas can and matches were also found in the auto.
The same area was searched, but on a smaller scale, immediately following the boy's disappearance, Mendoza said. The boy's parents were in the middle of divorce proceedings and had been sharing custody of the child.
A $20,000 reward approved by the Los Angeles County Board of Supervisors Tuesday was offered for information that helps authorities locate the child.
