CARLISLE, Pa. (AP) — A coroner has determined an 82-year-old woman who died at a central Pennsylvania hospital in February was strangled to death with a cord in her bed.

The suspicious death was reported at Holy Spirit Hospital in East Pennsboro Township on Feb. 28. Cumberland County Coroner Charles Hall says this week that an investigation has determined the woman had an oxygen and blood pressure cord wrapped around her neck and a pillow on her face.

Hall says the cause of death is strangulation, but authorities don’t know if it was suicide or something else. The woman’s name hasn’t been released.
