American crime/thriller movie from the 80s or 90s. White male protagonist wearing a jacket. Opening scene: he points a gun at a couple (or maybe one man) in bed, possibly handcuffed, seems like resolving a crime situation, but doesn’t kill them. He burns some money and leaves. Then there’s a close-up of him stopping on a desert highway and releasing a live cockroach onto the road. Later he goes to a roadside bar and puts something in a mailbox outside
