MACHIASPORT, Maine — The Maine medical examiner’s office has determined that an elderly couple found dead in their Machiasport home on May 2 accidentally suffocated.

The cause of death for Donald Dill, 84, and Mary Dill, 90, is “positional asphyxia and the manner [of death] for both is accidental,” Mark Belserene, administrator for the chief medical examiner’s office, said Friday.

“Mr. Dill reportedly became entrapped under a large heavy dresser that fell forward on him. Mrs. Dill was apparently attempting to remove the dresser and also became entrapped,” Belserene said.

The couple’s son found his parents about 9:35 a.m. on May 2 when he went to the home, according to the original news release from the Washington County Sheriff’s Department.

No further information was available from the Sheriff’s Department or Belserene.

Positional asphyxia refers to a situation where respiration is compromised either because the chest and/or diaphragm is prevented from functioning normally or the upper airway is blocked due to abnormal positioning of the body, according to the U.S. National Library of Medicine.
