A 30-year-old man found stuck in a wall void space near Brewjee and Maya Cinemas in Salinas was taken to the hospital after police responded to the scene around 6:15 a.m. Sunday.

According to initial information from the Salinas Fire Department, the man fell from the roof of Maya Cinemas near the lettering. It was estimated that he slid down at least 22 feet.

Officials said he was not an employee, and it remains unknown why he was on the roof.

Officers reportedly heard muffled calls for help while getting coffee Sunday morning, leading them to the man’s location. He told responders he had been stuck there since about 9 p.m. the night before, meaning he may have been trapped for roughly 12 hours.

Authorities said the man was found in what was described as a wall void space. There was a scuttle hatch nearby, and the man said he was stuck between metal beams and could not move. It remains unclear whether he slipped or fell into a 1-foot-by-2-foot opening.

Rescuers worked for about two and a half hours to extract him from the space. He was then taken to Natividad Medical Center with a minor back injury.

The breached wall was reportedly being patched afterward. The damaged area is located on the exterior wall between the two businesses.

Fire officials said it took them two and a half hours to get him out.

Authorities have not yet released additional details, and the incident remains under investigation.
