The Flathead County sheriff released the name of the woman whose body was found on a barge in Flathead Lake Monday. The barge had been docked along the shoreline in Lakeside.

NBC Montana reports the deceased is identified as Shawntal Johnston, 38, from Lakeside.

The sheriff says the reason Johnston died has not been determined. Investigators are still waiting for autopsy and toxicology results from the State Medical Examiner’s Office and Montana State Crime Lab.

The death remains under investigation by the Flathead County Sheriff’s Office.

When barge workers called dispatchers, they said her body was clothed but she appeared to have been beaten.

At that time, the sheriff said nothing indicated foul play.
