PHOENIX — Rescue crews say a man has been found dead Saturday after a partial roof collapse at a large commercial building in west Phoenix earlier this week.
Shortly after 9:30 p.m. Wednesday, Phoenix fire crews arrived on the scene of the reported roof collapse near 43rd Avenue and Van Buren Street amid heavy monsoon storms.
Search and rescue crews spent several days searching for the man who was unaccounted for before fire officials say he was located in the debris Saturday afternoon.
The Phoenix Fire Department gave an update on this incident Saturday afternoon. Watch in the player below:
A woman told ABC15 Thursday that her brother, 22-year-old Oswaldo Montoya, was the person crews were searching for. She says he was working as a forklift operator at the time of the collapse.
Phoenix firefighters say they have strong evidence that Oswaldo was the man found dead at the scene, but the official confirmation will come from the medical examiner's office.

The Arizona Division of Occupational Safety and Health (ADOSH) says it is investigating the partial roof collapse.
ADOSH investigates whether or not any health or safety regulations were violated and investigations can take up to six months.
