I haven’t read anything about it, so I can’t say for sure, but I work in the Lewiston area and I’ve heard both the bowling alley and bar to be more “local” oriented businesses.
The Walmart distribution center is a weird one though, because it’s not really a store front.
Whatever his motivations are, it breaks my heart to see it happen in our neck of the woods.
I believe the suspect that the police have identified was a firearms instructor at a military base down in Saco.
