Murph's Theory Edit
As a 12 year old Kid Mayor, Pierre invented and fell in to a pyramid shaped bucket where he drowned. After, Pierre did push ups every day until he came back to life.
Caldwell's Theory Edit
Originally born Pierre Ahmed Head, Pierre was 12 Year Old Kid Mayor of Silent Hill. Pierre erected the first mini golf course in Silent Hill, it featured a windmill, sinking ship and, Pierre's pride and joy, a pyramid. Unfortunately, as the pyramid was being lowered into the course during the grand opening, Pierre trips trips and is crushed to death by the pyramid, causing him to haunt Silent Hill thereafter. The reason he's so buff is because he spent years trying to get the pyramid off him.
Emily's Theory Edit
Pierre Ahmed Head was working on a huge metal sculpture. He started the sculpture at the vagina, before long he was so turned on by what he had sculpted he tried to eat out the giant metal vagina by sticking his whole head into it but got stuck.
