Mary Tisdale, the woman who went missing from her assisted living facility last month, was found in Leakin Park last weekend.
She had died from exposure to the elements and hypothermia, according to a report by WBFF-TV.
On Sept. 25, Baltimore County police said Tisdale, 62, walked away from her residence and was quickly reported missing on Sept. 20.
Tisdale suffered from dementia, according to a news release. She didn't tell anyone where she was going.
"She suffers from medical conditions that may cause confusion, and she may not recall where she lives," the Sept. 25 release stated.
