Chetek, Wisconsin - Investigation into the reported unidentified flying object near the Rice Lake Air Center last week has ended without a determination for what it may have been.

"Our officers saw some strange lights," said Barron County Sheriff Tom Richie. "That is what we're leaving it at."

On Monday, April 13, around 9:30 p.m., the Barron County Dispatch received calls about a possible UFO sighting. Law enforcement officers observed strange lighting and several members of the public also reported seeing it. A Chetek family, the Hausers, was one group of individuals who reported seeing the UFO. They described it as a large, fast-moving, tear-drop shaped object hovering low not far from their vehicle as they were traveling near the Rice Lake Air Center.
