The search continues for a Day County woman who has been missing now for two weeks.
Amy Dougherty, 46, of Andover has been missing since she left for work on Dec. 23. She works in Bristol and was driving during blizzard conditions. She was driving a black 2002 Chevy Trailblazer.
Day County Chief Deputy Jerred Schreur said Wednesday that ground and air searches have covered the area between Andover and Bristol extensively.
“We’re working on trying to get a different approach,” Schreur said.
Area fire departments, volunteers, Codington County Search and Rescue, the Civil Air Patrol and the Lake Area Technical College aviation program have assisted in the search along with private pilots.

Schreur said some of the search techniques have involved drilling holes in the ice on sloughs and using sonar to check for signs of a vehicle. Officials are working to fine tune sonar equipment to expand the search area in the water, he said.
“It’s possible she made it further out and then went through the ice,” he said.
Schreur said that if Dougherty went off the road, evidence of where that happened was likely quickly covered because of the blizzard.
Searches have covered alternate routes between Andover and Bristol, and officials have checked into the possibility that Dougherty was heading elsewhere, but have found no evidence of that.
