Marley "The South Bend Shovel Slayer" (Roberts Blossom) was certainly not an asshole.
Buzz: You ever hear of the South Bend Shovel Slayer?
Cousin: No.
Buzz: That's him. Back in '58 he murdered his whole family and half the people on the block with the snow shovel. Been hiding out in this neighborhood ever since.
Cousin: Well, if he's the Shovel slayer, how come the cops don't arrest him?
Buzz: Not enough evidence to convict. They never found the bodies, but everyone around here knows he did it. And it will just be a matter of time before he does it again.
Cousin: What's he doing now?
Buzz: He walks up and down the street every night salting the sidewalks.
Cousin: Maybe he's trying to be nice.
Buzz: No way. See that garbage can filled with salt. that's where he keeps his victims. The salt turns the bodies into mummies.
