Authorities in Lincoln say a 69-year-old woman's death likely was caused by exposure to the elements.
Police Captain Allen Soukup said Barbara Rhodes could have been outside for several hours before she was found dead near the retirement home where she lived.
Rhodes was found dead shortly after 4 p.m. on Feb. 5. It was unclear Wednesday when Rhodes went outside or why she couldn't go inside.
Temperatures hovered between 22 and 26 degrees that day and between ten and 26 degrees a day earlier.
The retirement home's management office said doors to the retirement home are locked from 9 p.m. to 6 a.m. Spokeswoman Jordan Hanson said if residents forget their keys, they can ring a doorbell at the front door and a manager will answer. Hanson said a manager is on duty 24 hours a day but residents are not closely monitored in the independent-living center.
