A manhunt is intensifying for the gunman who allegedly killed a bartender and three patrons at a bar in southwestern Montana, authorities said.

In Sunday’s press conference at the Deer Lodge County Courthouse, Attorney General Austin Knudsen says the suspect in the Owl Bar shooting is still on the loose.

Four people were killed in the attack inside the Owl Bar in Anaconda, Mont. The authorities are still searching for the suspect, an Army veteran who lived nearby.
