Authorities are once again searching a South Pasadena park for clues that they hope will help them find a missing 5-year-old boy.
Aramazd Andressian Jr. has been missing for nearly a month.
His father, Aramazd Andressian Sr., was found unconscious at Arroyo Seco Park on April 22nd — but the boy was nowhere to be found.
The park has already been searched as part of the investigation but officials are hoping to uncover any new scents or clues the park might yield.
"At this point because of the recent information we received from a tip, that's why we're back here today," said Lieutenant Joe Mendoza with the L.A. County Sheriff's Department at a press conference early Thursday morning.
The search began at 6 a.m. Thursday morning and is expected to take most of the day. In addition to deputies and dogs, a drone is being used to scour areas that are difficult to access by foot.
Andressian Sr. was initially arrested on suspicion of child endangerment but later released.
On Wednesday the boy's mother, Ana Estevez, made a tearful public plea for her son's safe return.
Authorities say the boy was last seen with his father at Disneyland on April 20.
