LOS ANGELES (AP) — An attorney for a man arrested on suspicion of killing his 5-year-old son, who has been missing for two months, says his client is innocent.

Robert Nardoni said Saturday that 35-year-old Aramazd Andressian Sr. is adamant that he never harmed his child.

Andressian was arrested Friday afternoon in Las Vegas and is being held there on $10 million bail.

A Los Angeles County sheriff’s spokeswoman wouldn’t say what evidence led to Andressian’s arrest. A news conference is scheduled for Monday.

Investigators have been searching for 5-year-old Aramazd Andressian Jr. since his father was found passed out in a park in South Pasadena, California, on April 22. Sheriff’s officials say the father took prescription pills and was found in a car doused in gasoline.
