A 58-foot female finback whale that washed up dead along an East Hampton beach Sunday may have died from blunt force trauma caused by hitting a vessel, according to an examination conducted Monday by marine biologists.

"There is evidence that human interaction may have been a contributory factor to her death," said Robert DiGiovanni, executive director and senior scientist with The Riverhead Foundation for Marine Research and Preservation.

The foundation conducted a necropsy on the mammal Monday after reports of a beached whale along a stretch of beach in Napeague came in Sunday around 8 a.m.

Scientists have sent out tissue samples collected from the whale for further study, but a complete analysis may pose a challenge because the whale's body was heavily decomposed, and it is believed to have been dead for at least two weeks, DiGiovanni said.

He said the whale had "blunt force trauma" on the left side of her body near her head, which indicated "interaction with a vessel of some kind." He said the whale also had "entanglement" markings on her body that were likely present well before her death.
