A Massachusetts man was found not guilty on charges in connection with a incident several years ago that resulted in a teenager losing her arm to the boat's propeller in Boston Harbor.

Benjamin Urbelis, the owner of the Naut Guilty, was found not guilty of operating under the influence and operating a vessel on Wednesday.

Urbelis, 35, had pleaded guilty earlier to furnishing alcohol to minors; however, a judge continued that without a finding for one year and ordered him to attend Alcoholics Anonymous.

The charges stem from a May 2015 incident in which a then-19-year-old from Auburn lost her right arm in the boat's propeller.

Last month, Alexander Williams, 26, entered a guilty plea in his role in the accident. According to the Suffolk County District Attorney's Office, Williams started the boat, but failed to put it in neutral as the victim swam back to the boat and tried to climb aboard. The propeller pulled her underwater.

Williams also admitted in court to furnishing alcohol to minors, as well as charges of negligent operation and tampering with evidence. The judge in that case placed Williams on a two-year probationary term.
