WARREN, Maine — A 74-year-old inmate from the Maine State Prison who was hospitalized for an undisclosed illness on Feb. 28 has died, according to the Maine Department of Corrections.

Robert Storer was transported and admitted to Pen Bay Medical Center in Rockport due to ongoing health issues and died Tuesday, according to a press release from the corrections department.

Storer was serving a 15-year sentence which started on April 3, 2007, for gross sexual assault and unlawful sexual contact.

The state medical examiner’s office has been contacted.

Judy Plummer, public affairs coordinator and director of special projects for the corrections department, said it is standard procedure to have the medical examiner look into any death of an inmate. She said she could not discuss the medical issues of a prisoner because of privacy laws.

Judy Garvey, co-coordinator of the Maine Prisoner Advocacy Coalition, said she was not aware of any issue surrounding Storer. She said the only question she would have is what type of care and treatment he received. Garvey said that, through talks with other prisoners and family members, prisoners are not sent out for specialized treatment as often as would be expected.
