Irish woman Catherine McCarty, 43, who suffered multiple injuries after her car was left in the cold overnight in February, was left for more than an hour in a hot car and was later found dead by her husband, police said.
Ms McCarty died from hypothermia after she was left alone in the vehicle for more to two hours, with her husband taking her to hospital, gardaí said.
A post-mortem examination found the body of the woman had been “subject to a hypothermic reaction”, a statement from the Corcoran Coroner’s Office said.
The woman’s body was later discovered by her brother, who was taking a walk along a road in the county.
Her husband has been charged with failing to provide a breath sample and has been bailed until November 20.
The couple had been married for almost five years.
The Corcorant reported on Tuesday that Ms McCarty was a former employee of the Coronet newspaper.
A spokesman for the company, which owns the Coronation Street, said it was “deeply saddened” by the news of Ms McCarthys death.
“Our thoughts are with the family and friends of Catherine,” the spokesman said.
