Sheriff Says 'No Indication' Ryan Mallett Death Due To Riptides

Ryan Mallett's death does not appear to have been the result of violent riptides in Florida waters ... according to authorities, the belief is the tragedy was all simply a freak accident.

Okaloosa County Sheriff Eric Aden said in a video statement Wednesday there was "no indication of dangerous conditions" in the Destin area where Mallett drowned on Tuesday.

"We were under a yellow flag," Aden said, "which is a just swim with caution."

"It just seems to be just a tragic accident and not something to do with the conditions of the surf or tides or currents."

Initial reports said Mallett was among a group of swimmers who had been out in the ocean struggling to make their way back to shore. Mallett, authorities said, went underwater while fighting to return to safety -- and when he was eventually pulled out, he was unresponsive. He later was pronounced dead at a local emergency room.

Many had believed dangerous and unseen riptides were what caused the tragedy ... but Aden insisted those were "misperceptions out there."

"There were no indications of any 'riptides,'" Aden's office added in a written statement.

Authorities also released some body cam footage Wednesday from the incident ... showing the beach's conditions as officers raced to the scene.

Mallett's death rocked the sports world ... everyone from Tom Brady to Rob Gronkowski to Bill Belichick mourned his passing in the hours after the news broke.
