More than 20 people were sent to the hospital with two in serious condition after the deck at a popular sports bar came crashing down into the water Thursday night.
In the light of day, what's left of a popular Miami Sports Bar deck calmly lies in Biscayne Bay, but last night it was chaos.
Anthony Herrera, a witness to the crash, told NBC news what he saw.
"You just hear crunch, crunch, curiosity and then bam, pillar coming down, pillar, pillar and people screaming, people yelling.. pieces of wood hitting the water."
Cheering on their home town Heat in the NBA finals, nearly a hundred people packed the deck of Shucker's Bar and Grill Thursday night.
Then the deck gave way.
Marie Torras also witnessed the event. "When we looked, part of the deck just caved in...there was a huge splash... there were people in the water."
Bystanders jumped into the water to help.
Eric Williams was one of them. "I actually went into the water. And we - we pushed people up. My son was pulling people up - out of the water. Even some of the first responders. Cause when we got in there --- little slimy."
First responders immediately began assessing those injured. Chief Jose Herrera of the Miami-Dade Fire Department said, "they were able to assess the scene, and start rescuing people."
Chief Bob Daniel of the North bay Village Police Department said, "the patrons who were dining on the deck, fell into the water, some sustained injury.. fortunately none were life threatening."
Today investigators are back on the scene, taking pictures of the splintered wreckage from the water.
They are searching for any clues as to what may have caused the deck to collapse.
