According to the Cape and Islands District Attorney's Office, the Dennis Police Department received a 911 call around 9:01 p.m. on July 21 that a boat had crashed into a jetty in Sesuit Harbor and that a 17-year-old girl was unaccounted for.
The U.S. Coast Guard, the Dennis and Sandwich fire departments, and the Barnstable County Dive Team were involved in the response off Cold Storage Beach in Dennis.
The teen's body was recovered from the water by the regional dive team, with assistance from Dennis Fire-Rescue personnel, around 11:30 p.m.
A preliminary investigation revealed that the vessel -- a Regulator equipped with two outboard 250 horsepower engines bearing an Alabama registration -- was occupied by six people at the time of the crash, which occurred at the jetty by the channel leading to the Northside Marina in Sesuit Harbor.
The DA's office said other occupants of the boat were treated at Cape Cod Hospital. At least one boat passenger, a teenage male, had a head laceration.
The cause of the crash is not known at this time.
