I'm pretty sure it's not a smart idea to steal your plans from the bad guys on "Scooby Doo".

31-year-old Shaun Miller from Hyannis, Massachusetts has been on the run from the cops since he was indicted on heroin trafficking charges in April. Now we know why they haven't caught him: Shaun has been hiding in plain sight by disguising himself as an elderly man.

Like, he's been wearing a mask that had fake gray facial hair, aged skin, and liver spots whenever he leaves the house.

Unfortunately for Shaun, the cops figured out he was in South Yarmouth, Massachusetts last Thursday and they surrounded the house, ordering him to come out. He walked outside in his mask, and at first the cops thought it really was an old man, but then they realized it was Shaun.

He was arrested and he'll be locked up until a hearing next week.
