The TV did say the murders occurred in OP's old home town, he's presumably plucking his preferred pumpkins from the previous precinct to prevent the probability of them being properly identified.

It's 2022, Halloween decorations are getting more gory, realistic and ambitious. I'm sure even if someone had an inkling of "Hey... This seems a little too real", they would just dismiss it as impressive special effects.

No one ever questions why my headstone decorations are up year round, or why there's more each year.

Spirit of the holiday and all that.
