A 95-year-old woman has died of hypothermia after she walked away from an assisted living facility in London. Laurel County Coroner Doug Bowling tells local media outlets that Dorothy McKnight died of exposure and was found outside of a neighbor's home Monday morning. Bowling says McKnight left her Laurel Village assisted living apartment early in the morning and walked about 100 feet to a neighbor's porch, but fell off the porch and wasn't dressed for the cold. It is unclear how long McKnight was outside before her body was discovered. The assisted living facility, Laurel Village, said in a statement that McKnight had lived there for almost 10 years and an investigation is underway into her death.
