Police after investigating the cause of death of a local girl after her mangled body washed ashore on South Beach early Monday morning.

The police have no leads as to what caused the death of Christine W. Watson, 17, but are strongly suggesting that the cause was not a shark attack.

"No sharks have been sighted in that area in a long time," Amity Police Chief Martin Brody said.

Watson was last seen by Christopher P. Hoggenbottam III after the two had left a party at South Beach.  Watson and Hoggenbottam had decided to go for a swim but Hoggenbottam passed out before entering the water.

"She was running into the water," Hoggenbottam said, "and next thing I know the police found her mangled body."

Witnesses at the party said there had been heavy drinking and possibly marijuana. 

When asked about what could have been the cause of Watson's death, Brody said that packs of wild dogs are common in the area but was not sure of that factoring into the case.

At this time, there are no suspects in the case and police hope to find more information after the autopsy.  Watson's body was transported to a coroner's office to find the cause of death.

In the meantime, police are encouraging people to go to the beach as people are in no danger of similar attacks. 

"Our lovely beaches will remain open for swimming," Brody said, "pending the outcome of the investigation."
