A medical examiner will determine what killed an 89-year-old woman who walked away from her Lee's Summit home during bitter cold weather over the weekend.

Police issued a Silver Alert Sunday for Jeannette Gauss, who was last seen at her home Saturday evening. Her body was found Sunday about 10 blocks from her home.

Gauss had dementia, Alzheimer's disease and high blood pressure.

Police say the cold weather likely contributed to Gauss' death because she left her home in a nightgown and no shoes.
