MIAMI — A third victim of a massive parking garage collapse at a Miami college died this morning, just hours after rescuers pulled him from beneath piles of twisted steel and crumbled concrete, police said.

Samuel Perez, 53, had been trapped in the collapse Wednesday at Miami Dade College. He was beneath the rubble for about 13 hours, communicating with rescuers before he was taken to a hospital. He was first discovered after workers heard his cries, and crews were saddened to hear he had died, said Miami-Dade Police Lt. Rosanna Cordero-Stutz.

Authorities said they no longer expected to find anyone else alive and expected to pull a fourth person from what remained of the five-story structure that had been under construction. One worker still is missing.
