A Suwanee man suffered severe injuries to his feet, one of which was “a complete amputation,” after a boating incident Saturday on Lake Lanier, according to authorities.

Hall County Sheriff’s Office deputies responded after 4:30 p.m. Saturday to Bolding Mill Park to a report of traumatic injury.

Sheriff’s Office spokeswoman Deputy Nicole Bailes said Shane Malloy, 19, had “a complete amputation” to one foot and had severe lacerations to the other foot.

“Deputies suspected alcohol and notified (Georgia Department of Natural Resources) of the accident,” Bailes wrote in an email. “Upon further investigation by DNR, it was determined that the operator of the vessel was impaired.”

William Craven, 19, of Cumming, was charged with boating under the influence of alcohol, reckless operation of a vessel, having insufficient personal flotation devices and littering.

He was transported to the Hall County Jail, where he has since posted an $8,300 bond.

DNR Cpl. Adam Loudermilk said authorities believe Malloy fell out of the the boat and was injured by the boat.

“It is undetermined at this time as to the exact cause of the accident and injury to the victim,” Bailes wrote in an email.

Malloy was airlifted to Grady Hospital in Atlanta. Loudermilk was unsure of Malloy’s current condition Sunday afternoon.
