After reviewing all of the evidence, homicide investigators presented the case to the Los Angeles County District Attorney's Office and obtained a murder filing against Andressian Sr., sheriff's officials said Friday. It wasn't immediately clear what prompted the arrest. Aramazd Andressian Jr. was last seen in Disneyland with his father on April 20, according to CNN, who was set to return the boy to his estranged wife two days later after a week in his care. The father's attorney called the disappearance a mystery and has said his client had gaps in his memory. The Los Angeles County Sheriff's Department says the father of a 5-year-old who has been missing for two months has been arrested on suspicion of his son's murder. His gray 2004 BMW sedan was found nearby with its interior and exterior doused with gasoline.
A day earlier, his vehicle had been spotted at Cachuma Lake - 120 miles northwest of Los Angeles - but surveillance footage subsequently showed he went there alone.
Arroyo Park was also searched a second time on May 18 by search-and-rescue crews, a scent and cadaver dog, and a drone, but nothing was found during the hourslong effort.
Helicopters and dive teams were deployed to Lake Cachuma, an artificial lake about 15 miles northwest of Santa Barbara, after Andressian said he traveled there with his son.
They also are asking anyone with information regarding the murder of Aramazd Andressian Jr., to contact the department's Homicide Bureau at 323.890.5500, or to provide information anonymously through "Crime Stoppers" by dialing 800.222.TIPS (8477) or by using the website.
Police and sheriff's deputies conducted an extensive search of the park for Aramazd but didn't find the boy.
Almost a week after the boy was reported missing, Andressian released a statement through his attorney.
"My family and I are heartbroken and grief-stricken that Aramazd Jr.is missing and may be in harm's way", he added. "I can only speculate that I must have been attacked in the park, given my unresponsive state and subsequent physical condition". Andressian Sr. remains adamant that he had nothing to do with the disappearance of his son. Officials planned to discuss the case in more detail at a scheduled press conference on Monday. "There are no words to describe how devastated and broken I am".
Ana Estevez, Ara's mother, told NBC4 Friday in statement that she's grateful for the support and prayers.
'To my son, this message is for you my love: be fearless, honey, ' Ana Estevez said through tears on May 18. "I am counting the days until I see you honey and I will never stop looking for you".
