Boat captain arrested months after fatal parasailing accident in the Keys

Newly obtained video shows family going up on parasail

MARATHON, Fla. ā€“ A boat captain has been arrested, several months after a woman was killed and her son and nephew were injured in a parasailing accident in the Florida Keys, Local 10 News learned on Thursday.

Local 10 News obtained the arrest warrant for Daniel Gavin Couch, 49, which shows he is charged with one count of manslaughter and five counts of violating commercial parasailing statutes.

Newly obtained video shows the moment the family went up in the parasail.

According to a report by the Florida Fish and Wildlife Conservation Commission, ā€œThe captain cut the line tethered to the three victimsā€ on May 30 off the coast of Marathon because the parasail was ā€œpegging.ā€

That is a phrase used to describe when a parasail turns into a sail in high winds and could potentially drag the boat.

The woman and two children were dropped and ā€œdragged through the water by the inflated parasail...through and across the surface of the waterā€ before colliding with the Old Seven Mile Bridge, the report states.

According to the report, onboard the 31-foot boat were nine people from Schaumburg, Illinois.

Authorities identified the woman who died as Supraja Alaparthi, 33. Her 10-year-old son, Sriakshith Alaparthi, was also parasailing with her. The 7-year-old boy who was airlifted to Nicklaus Childrenā€™s Hospital is Alaparthiā€™s nephew, identified as Vishant Sadat.

FWC officers said Supraja Alaparthi was declared dead by the time a Good Samaritan boat captain arrived to help.

Couch worked for Lighthouse Parasail Inc., which is based in Marathon and had departed from Captain Pipā€™s Marina & Hideaway that day.

According to the warrant, Couch violated several commercial parasailing statutes.

The weather, specifically the wind speed, was a ā€œkey contributing factorā€ in the accident, the warrant stated. Authorities said Couch did not pay attention to a weather alert that day and had said his VHF radio was not turned on at the time.

Authorities said he claimed he did try calling 911 but his phone wasnā€™t working.

The victimā€™s family has filed a lawsuit against the parasail operator.

ā€œThere is no excuse for the negligence and disregard for public safety that was shown in this case,ā€ FWC Regional Commander Major Alberto Maza said in a statement released by the agency. ā€œMy prayers go out to the families of those involved in this terrible accident. Our investigators conducted a thorough investigation, and the charges today hold those responsible for this tragedy accountable.ā€
