UPDATE (Sun. 4:25 p.m.) - Morro Bay Police were unable to locate the man last seen trespassing on Morro Rock Saturday evening.
Crews resumed their search at daybreak with a drone to survey the western top half of the rock with Habor Patrol, but were unable to locate anyone.
Officers closed down the parking lot and monitored the area through the night, but believe the man somehow climbed down and slipped out sometime in the middle of the night.
If you have any information, you are asked to call the Morro Bay Police Department.
UPDATE (9:09 p.m.) - The man has not yet descended from Morro Rock, according to Morro Bay Police.
Officers launched a drone and were able to get a visual of the subject, but were unable to identify him or his condition or make contact.
Fire crews were forced to call off the search due to dangers of climbing the rock at night.
Authorities say first responders will continue the search at first daylight tomorrow morning.
However, police officers say they will stay in the area overnight to monitor the situation and check for possible movement.
