Mary Mara reportedly faced a tragic incident before drowning, the authorities confirmed.

The New York State Police released a press statement following the discovery of Mara's body in the St. Lawrence River. It revealed that they conducted a preliminary investigation and determined that there were no signs of foul play.

However, it said that the investigation was still ongoing.

A few days after Mara's tragic death, her representative disclosed further details about the heartbreaking event.

In an exclusive interview with a news outlet, the actress's representative Craig Dorfman said that the authorities concluded that the abrasions on her face and body suggested she probably died after suffering blunt head trauma.

Police assumed that she slipped while trying to get out of the water and hit her head, causing loss of consciousness. With that, she fell back into the water and drowned.

However, PEOPLE later confirmed that the report was inaccurate, with the police saying there were no signs of trauma on her body when she was found.

As of press time, the authorities have concrete evidence of what object hit her head - or she hit as she fell - they clarified that no foul play was involved.

"The preliminary investigation suggests the victim drowned while swimming. The victim's body showed no signs of foul play and was transported to the Jefferson County Medical Examiner's Office pending an autopsy to determine an official cause of death. The investigation is continuing," the previous release said.

The 61-year-old's representative also said that they do not believe drugs or alcohol were involved in the accident.
