CHARLOTTE COUNTY, Fla. - A day on the Gulf took a terrible turn after a 54-year old jet skier collided with a motorboat and lost part of his leg. The impact also threw four boaters into the water. It happened off the coast of Englewood.

The Florida Fish and Wildlife Conservation Commission spent hours Sunday, investigating the crash.

First responders met the boaters at Stump Pass Marina after they were rescued by another boat. 

Wink News spoke exclusively spoke to the son of the injured jet ski rider, 15-year old Mark Hollis.

Hollis says his family is on vacation from Kansas City and saw the whole thing happen in front of him. He was so shaken he could barely put it into words. 

"We were just riding jet skis. My dad took a right turn and a boat hit him. We were just about to go out to the Gulf of Mexico to ride the jet skis when it happened," he said.  

According to the jet skier's son, his father collided with the motorboat carrying four passengers, a man and two women in their 40's, along with a 12-year-old boy.

All five people were thrown into open water. The jet ski rider's leg was severed in the crash. Hollis says a person in a sailboat witnessed the accident and quickly came to their aid. He then took them back to Stump Pass Marina in Englewood.  

Dee Hawkins with Charlotte County Fire and EMS says a 911 call came in around 4:30p.m. and two marine units from Charlotte County and Englewood responded immediately. 

"Anytime we have an amputation that warrants a trauma alert. And so the chopper was called. But en route to our location that patient experienced cardiac arrest," she said.

The victim was taken to Englewood Community Hospital where Hawkins says he was resuscitated. Shortly after, the helicopter was called back for one of the boaters who was also in need of medical attention. 

"40-year-old female that was on the boat that was experiencing some chest pains, from the trauma," she said.

Charlotte County Fire and EMS says the injured boater was airlifted to Lee Memorial Hospital and the jet ski rider has been transferred to Blake Memorial in Manatee County.
