BOWDOINHAM, Maine — A Bowdoinham woman who was attacked inside her home Monday morning died overnight at Maine Medical Center.

Beulah “Marie” Sylvester, 55, died as a result of the attack at her mobile home at 946 Post Road, according to a news release from Stephen McCausland, spokesman for the Maine Department of Public Safety.

Sagadahoc County deputies were called to the home at 8:52 a.m. Monday for a report of someone in cardiac arrest, Chief Deputy Brett Strout of the Sagadahoc County Sheriff’s Office said Tuesday.

Deputy Mike Fitzpatrick found Sylvester unresponsive, and while attending to her, “determined that there was more to the initial call than the reported cardiac arrest,” Strout wrote in an email.

Based on Fitzpatrick’s concerns, the sheriff’s office notified the state police.

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

The state medical examiner’s office began an autopsy Tuesday. More work must be done before a cause of death can be announced, McCausland said late Tuesday afternoon.

The dirt driveway of the mobile home, off a rural road in Bowdoinham, was lined with trucks and SUVs on Tuesday morning as detectives from the Maine State Police Major Crimes Unit investigated the incident. Investigators collected evidence and sent it to the state crime lab for evaluation.

Just after 11 a.m., a man who identified himself as Sylvester’s son-in-law emerged from the home and told the Bangor Daily News that the family would have no comment and would “just let the state police handle it.”

No charges were filed as of 4:20 p.m. Tuesday, and police said there was no threat to public safety.
