Changed his mind, sure. More like got paranoid after 'relaxing' in the green, grassy park realizing he is carrying around the head of a goat.
Canadian police solve severed goat heads mystery - Yahoo! News: "VANCOUVER, British Columbia (Reuters) - A lazy worker, not a satanic cult, was responsible for severed goat heads that caused a scare at a Vancouver-area school, Canadian police said on Monday.
Police were called in after goat heads were twice found on a bench outside a school in nearby Chilliwack, British Columbia, prompting fears in the suburban community that it had been targeted by a satanic animal killing.
A 19-year-old worker at a local slaughterhouse has admitted he took the two heads with the intention of having them mounted, but then changed his mind and left them at the school in hopes a janitor would dispose of them."
