COLD SPRING, MINN. - On Sunday, three days after Cold Spring police officer Tom Decker was slain on duty, small groups of law enforcement officers and volunteers picked their way through brush along the Sauk River, just down the block from where Decker died.
They were still searching for the 20-gauge shotgun allegedly used by Ryan Michael Larson to shoot the 31-year-old officer late Thursday as he and another officer responded to a report of a suicidal man.
The officer's slaying, which investigators have described as an ambush, has led to a search not only for the murder weapon, but for answers in this small community.
"I think there's more story; we need to know, why did it happen? What snapped in this person?" resident Wayne Krone said Sunday while working at Winners Sports Bar. "The town needs closure. We need to start the healing process."
About 9 p.m. Thursday, officers first responded to a report of a suicidal man, but couldn't make contact with Larson, 34.
He lived in an apartment above Winners bar on Main Street, where Decker had made his last stop just before heading to check Larson's welfare, along with another officer, about 45 minutes after the first officers left.
Decker, a father of four, was shot in a parking lot behind the bar and a neighboring bowling alley. He died at the scene.
Within an hour of the shooting, Larson had been arrested in his second-floor apartment, apparently after leaving and coming back. It remains unclear where he was during that time, and what happened to the shotgun believed used in the slaying.
