Four people have been confirmed dead and at least a dozen injured in a Coconut Grove boat collision, authorities said Saturday.
The boaters are believed to have been out celebrating the Fourth of July holiday when the crash happened late Friday near the Dinner Key Marina in Miami.
Rescuers were alerted by one of the boaters at about 10:45 p.m. He said he'd been hit by another vessel and that his 36-foot pleasure craft was taking on water, the Coast Guard reported. The man reported that the vessel that struck his boat did not stop following the collision.
Multiple law enforcement agencies responded to a chaotic scene. Officers plucked several people out of the water while struggling to determine how many were still missing.
"We kept getting report after report of more people in the water," Miami Fire Rescue Lt. Ignatius Carroll said.
Eight people were initially transported to Miami hospitals. Two adults, a male and a female, later died. Officials confirmed that 20-year-old Kelsie Karpiak was one of the victims who died in the crash. NBC 6 has confirmed another man who was fatally injured in the accident is the son of a Miami-Dade firefighter.
Commercial salvage crews found the second vessel believed involved in the crash. Two unconscious females were found on board and transported to a nearby boat ramp.
Coast Guard officials said they contacted the second boat's owner. They were told the owner's son had taken the vessel out Friday evening.
The search for the missing boater and any other possible passengers continued into Saturday.
Relatives of another female located her body in the water on Saturday, Jorge Pino, a public information officer with the Florida Fish and Wildlife Conservation Commission said.
Investigators located the body of another missing person later Saturday morning, Carroll said.
Names and ages of the deceased and injured were not immediately released.
"My understanding is they may have been out there enjoying the fireworks display, and typically after the fireworks are over, everyone makes a mad dash for the nearest marina," Pino said. "And unfortunately in the past we've seen where accidents have occurred during that time."
Pino said the time of the crash coincides with when boaters are typically making their way back to the marina, though the exact circumstances were still under investigation.
He said three boats in total were involved in the crash.
Carroll described a chaotic scene Friday evening as rescuers tried to determine how many people were in the water.
"The numbers kept growing and growing," Carroll said.
He recounted how one man waited anxiously at the dock to find out what had happened to his two grandchildren. Both arrived safely to shore.
"We were relieved to be able to let him know that they were OK," Carroll said.
