A number of people were rushed to the hospital and one man went missing at sea after two boats crashed in Key Biscayne.

According to authorities, two boats collided in the bay late Friday night.

“There was eleven patients that we needed to treat and assess. Ten of those patients were transported to area hospitals, two in critical condition, one minor, one adult, and there was also another minor that was transported to the hospital,” said Miami Fire Rescue Lt. Pete Sanchez. “At this time, we are currently still searching for a 12th victim. It’s an adult male that went missing at the impact point.”

The search continued into late Friday night into Saturday morning.

The crash is still under investigation. “At this time, we don’t know how the accident happened,” Sanchez said.

The U.S. Coast Guard was the lead agency in the search
