Massachusetts State Police are investigating after a passerby reported a dead body along the shores of Revere Beach Thursday morning.

At 5:57 a.m., a person walking along the beach across from Shirley Avenue in Revere found a dead body and notified police. Shortly after 6 a.m., state police arrived and found the dead body of a woman at the shoreline.

The body was removed from the scene Thursday morning to undergo an autopsy by the chief medical examiner. State police say their immediate observations did not reveal any obvious signs of trauma, and the Suffolk County District Attorney's Office said the death "does not appear to be the result of criminal conduct."

The deceased woman has been "tentatively identified" by state police, but authorities are withholding her name. They say the woman's relatives have not yet been notified.

An investigation into the death is underway by the State Police Detective Unit for Suffolk County.

This is a developing story.
