The victims killed during a shooting at The Owl Bar in Anaconda, Montana, range in age from 59 to 74, Montana Attorney General Austin Knudsen said in a news conference Sunday.

The victims, all local residents, have been identified as 59-year-old Daniel Edwin Baillie, 64-year-old Nancy Lauretta Kelley, 70-year-old David Allen Leach, and 74-year-old Tony Wayne Palm, a news release from Knudsen’s office said Sunday. The victims included a bartender and two customers, Knudsen said.

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