KCAL9’s Crystal Cruz reported from the scene.

Dozens of firefighters searched the storm drains in and around Bedford Canyon and Georgetown Road, authorities told Cruz.

The area is restricted to the public.

The boys were reportedly looking for a lost skateboard and allegedly fell down or went into the storm drain.

A passerby claimed to have heard screaming and called 911.

Firefighters told Cruz they also heard some screaming but communication soon went silent.

That’s when search crews suited up and went down several connecting storm drains.

Officials theorize the boys were able to get out of the storm drain on their own.

“We repositioned and determined that with multiple access points to exit the storm drain, we have called off our last entry,” Corona Fire Department Public Information Officer John Deyoe said.
