The Stearns County Sheriff’s Office is officially closing the investigation into the murder of Cold Spring Police Officer Tom Decker. Decker was conducting a welfare check near a downtown Cold Spring bar in November 2012 when he was ambushed, shot and killed. Police arrested Ryan Larson as a person of interest in the case but Larson was never charged. Officers then turned their attention to 31-year-old Eric Thomes. But, Thomes committed suicide in 2013 as police were closing in on him. A shotgun linked to the murder was also found on the family property where Thomes died. Thanks to WJON
