(ABC 6 NEWS) -- The man arrested in the slaying of a Minnesota police officer says he was sleeping at the time and authorities have the wrong man.
Ryan Larson says he is innocent in the death of Cold Spring police Officer Tom Decker.
Decker was shot Thursday night near a Cold Spring bar in what officials called an ambush. Police arrested Larson about an hour later.
Authorities say they don't have enough evidence to file charges at this time, but the investigation continues. They have not found the weapon used in the killing.
