Greendale Police Chief Rob Dams said Betty Borowski apparently became stuck under the vehicle after attempting to reach some keys that had fallen in her garage, the Milwaukee Journal-Sentinel reported Friday.

"She was pretty well wedged in there," Dams said of last Sunday's accident. "It looks like she crawled under head-first."

After a mail-carrier noticed Tuesday that the elderly woman had not retrieved her Monday mail, he contacted the police and a responding officer heard Borowski calling for help from her garage.

Firefighters were called to the scene and freed the woman from the vehicle, the Journal-Sentinel said.

The newspaper said Borowski was dehydrated, confused and may have suffered a heart attack during the incident, but her niece, Nancy DiMarco, confirmed her aunt was recovering from her ordeal at a Milwaukee hospital.
