Early this morning a Washington County Deputy shot and killed a man who was armed and making suicidal threats. Deputies received reports of a man with a gun threatening suicide at a Lake Elmo intersection. Officers attempted to deescalate the situation by speaking to the man first, followed by using non-lethal ammunition. Later a deputy fired and shot the man, who later died at Regions Hospital in Saint Paul. Chief Deputy Brian Mueller has yet to provide the reason the man was shot. The Bureau of Criminal Apprehension will provide more information after conducting initial interviews.
