Year: 2008
Location: Long Island, NY

It's wise to stay away from Walmart on Black Friday. In 2008, there was a raucous stampede at a Long Island Walmart after some 2,000 people stormed the store five minutes prior to its opening. In a tragic turn, a 34-year-old temporary employee was trampled to death, and other employees were knocked over by rowdy customers. It got worse—a woman who was eight months pregnant and only trying to buy supplies for her child was found unconscious near the store's entrance. 

She would later miscarry.
