Authorities find body of missing Alton woman

Police and volunteers used every search tool they had: ATVs, a drone, a helicopter, and search dogs to cover the more than 5000 acres surrounding the lake. A hunter found an unspecified article of her clothing Monday night, authorities said. That discovery gave a new direction to their search. Previous searches had concentrated in the area surrounding Hatten's car.

The case is only being investigated as a suspicious death and that foul play is not suspected at the moment. With no obvious signs of trauma, investigators believed the cold may have been a factor in her death.

"I think the indicators would be the exposure because of the temperature. The temperature at the time that we found her was in the 30s right here," Connor said. "Her car was found in a muddy field in a remote area. That makes it suspicious."

Authorities said there's no indication anyone else was with Hatten.

Connor said Hatten's body was found intact, but the Madison County Coroner's Office will determine the official cause of death.

Her disappearance drew nationwide attention. The hashtag #HelpFindAdria proliferated on social media.

There's still no explanation why she ended up in a place more than 20 miles from her home in a place she’d never been known to visit.

She leaves behind her husband and two grown children.
