STYX RIVER, Ala. — It was a deadly day on Styx River for 48 year old Robert Thompson, of Pensacola, who died after diving headfirst into the river on Sunday while tubing with friends.

“We haven’t determined a cause yet and are waiting on autopsy results to come back. We do know there is no evidence of foul play and will not know if alcohol was involved until the toxicology report comes back,” said Stan Vinson, Baldwin County Coroner.

Thompson had been tubing down the river when at some point, had stopped and climbed a tree about six feet off the ground and dove into the river. Vinson said his wife and friends were with him and watched him do it and we he came floating to the top, someone from the group immediately called 911.

“They had a nurse in the group who immediately began CPR and because of their location on the river, Thompson had to be floated down to where the paramedics could get to him. They tried to revive him but they weren’t successful. His body was taken to the Department of Forensic Sciences in Mobile. We really aren’t sure if the cause of death was from drowning or a injury to the head or broken neck,” Vinson said.

Where most of the tubing takes place on the river, it is wasit-deep, Vinson said, while there are other places deep enough for swimming, but the exact location of where Thompson was is not known at this time.

No other deaths on the river have been reported this year, Vinson said.
