State police said Tuesday that they will continue to investigate the death of a Bowdoinham woman found injured and unconscious in her mobile home Monday, but said there is no threat to the public at this time.

Police found Beulah “Marie” Sylvester, 55, badly injured at her home on Post Road. It was not known who alerted police, but the Sagadahoc County Sheriff’s Office confirmed that the initial call was that Sylvester had a heart attack. Her injuries, though, were more severe than that and police initially investigated them as an aggravated assault.

Sylvester was taken by ambulance to Mid Coast Hospital in Brunswick and transferred to Maine Medical Center in Portland, where she died.

Maine State Police Spokesman Stephen McCausland said an autopsy was conducted at the State Medical Examiner’s Officer in Augusta on Tuesday but “additional work remains to be completed before final conclusions are reached,” about the cause and manner of her death.

Detectives spent much of Tuesday in Sylvester’s home gathering evidence but McCausland didn’t discuss details. It’s not clear whether the woman lived alone.

“At this point, we’re still trying to determine what happened and how she was injured,” McCausland said.

Family could not be reached for comment.
