1 dead, 2 trapped in Fla. parking garage collapse Updated 2:00 PM ET MIAMI A fire official says one person has been killed in the collapse of a parking garage under construction at a Miami-Dade College campus and that two workers are still trapped. The two trapped workers were using cellphones to talk to rescue teams, Miami-Dade Fire-Rescue spokeswoman Griselle Marino said. Several other workers were hurt. The cause of the collapse on the Miami-Dade College campus was not immediately released. Four workers were taken to the hospital, including one in serious condition, Marino said. Three others were treated by paramedics at the scene. The large section of the four-story garage fell shortly before 11:40 a.m. No students were in the area at the time, authorities said. Earlier, Miami-Dade Fire told CBS4 in Miami that several people were trapped in the rubble, with Doral and Sweetwater Police on hand at the scene. "We've been here for a while," said Doral Police Chief Ricardo Gomez. If there's any good news out of this it's that this is a parking garage was under construction. Right now, we're doing a head count to see how many people are missing. The issue is the structural integrity of the garage has been compromised to the point that it's unsafe to get into the garage. Earlier, television reports showed several workers being treated by paramedics at the scene. Victoria Buczynski of Miami said she saw the collapse while she was working at Gurkha Cigars directly across the street from the construction site. "It fell to the ground like a house of cards," Buczynski said. The construction workers started running out, screaming. It was loud. Our entire building shook. The construction of the garage appeared to be nearly complete. Ground was broken on the $22.5 million project in February, and it was to be completed in December, according to Ajax Building Corporation's website. The first floor was to have classroom and office space. TV reports showed one large section of the concrete structure collapsed. The identity of the worker who died was not immediately released.
