Detectives are searching the home of a man whose 5-year-old son has been missing for nearly a week according to Los Angeles County sheriff's spokeswoman Nicole Nishida.
Sheriff's detectives served a search warrant on Friday at Aramazd Andressian Sr.'s home in South Pasadena where they say they were searching for "forensic evidence."
A scent detection dog has also been brought into the scene.
Aramazd Andressian Jr. has been missing since his father was found unconscious at a park last weekend. Aramazd Jr. was last seen leaving Disneyland with his father on April 20th.
The father was arrested on suspicion of child endangerment, however, he was released after detectives did not present the case to the district attorney.
Andressian's attorney says Aramazd Sr. is hoping for his son's safe return.
