Authorities recovered a man’s body underneath the Whale Harbor Bridge in Islamorada early Thursday morning.
The Monroe County Sheriff’s Office suspects the man committed suicide, said agency spokeswoman Deputy Becky Herrin.
The Sheriff's Office identified him as Christopher Rishell, 48, of Pembroke Pines. When deputies with the Sheriff's Office Dive Team found him, they discovered he had two 25-pound dumbbell weights tied to his right arm.
"There were no initial indications of foul play, according to Major Crimes detectives assigned to investigate," Herrin said. "The Medical Examiner’s Office will be doing an autopsy to determine Rishell’s official cause of death."
Deputies found Rishell’s vehicle, a 2012 Mazda, parked at the top of the bridge around 3 a.m. They found a cell phone and wallet on the top of the car. A pack of cigarettes was left on the railing of the bridge.
Crews with the U.S. Coast Guard and the Florida Fish and Wildlife Conservation Commission searched under the bridge for the driver.
Rishell's vehicle was taken to the Sheriff’s Office Plantation Key substation for further investigation.
