State police are investigating after a woman's body was discovered on Revere Beach early Thursday morning.
State police said they received a 911 from the passerby who made the discovery across from Shirley Avenue.
The woman, who has been tentatively identified by investigators, didn't show any obvious signs of trauma.
But, the Suffolk County District Attorney's Office said, the Office of the Chief Medical Examiner will work to determine the cause and manner of her death.
No other information was released.
