The driver of a speedboat that crashed on New York's Hudson River, killing a bride-to-be, the best man and seriously injuring the groom, has been charged with vehicular manslaughter amid police suspicions he was intoxicated while in control of the boat.

Jojo John, of Nyack, was charged with vehicular assault over the incident late on Friday night, said Rockland county sheriff's department chief William Barbera.

John, 35, may have been operating the boat while intoxicated, Mr Barbera said.

A body matching the description of bride, Lindsey Stewart, 30, was recovered from the water although police have not provided official identification.

It is believed she was thrown from the Stingray speedboat after it crashed into a construction barge near the Tappan Zee Bridge on Friday night.

Ms Stewart was due to marry art teacher Brian Bond, 35, who she had known since childhood, at a wedding on August 10 in two weeks time.

Mr Bond, who was knocked unconscious during the crash, is thought to have suffered a fractured eye socket in the crash, was said to be inconsolable after being told the news of his fiancee’s death.

Despite a serious head injury he managed to call emergency services following the crash.

The body of a man matching the description of best man Mark Lennon was found yesterday a mile downstream from where the bride-to-be was found.

Jojo John, who was driving the boat at the time of the incident, was charged by police in his hospital bed. Authorities believe he was intoxicated at the time of the accident and are awaiting the results of blood tests.

'At this point, we have probable cause to believe he operated the boat while intoxicated, and that's the basis for the charge,' Rockland County Undersheriff Robert Van Cura told ABC News.
