The Dahl Files

Cold cases from a small-town sheriff’s boxes. Some he got very wrong.

Four boxes of Sheriff Ray Dahl’s case files turned up on the Vesper Lake Historical Society’s back step, with a card on top in green ink. Each case is a printable file of exhibits. Read the statements, check the timeline, and decide what really happened.

“I got some of these wrong.”
