A runaway shopping cart killed a 66-year-old woman in China on Friday. The fatal accident was captured on a security camera at a Shanghai supermarket.

The video shows a woman stepping off a ramp escalator when a flatbed shopping cart behind her comes barreling down the ramp. The cart strikes the woman with such force that it throws her into a wall about 20 feet away.

The shopping cart was reportedly filled with 15 cases of drinks when its owners lost control of it, Xinhua reports. The three shoppers insisted on using their own cart instead of one owned by the supermarket, which has “anti-slip mechanisms.”  

Police have put two people “under restriction” since the incident. The woman was reportedly transported to a nearby hospital, where she died of her injuries.

Some say the accident may serve as a warning to customers who "dangerously use just one hand when tugging the trolleys," while others say the supermarket is partially responsible for allowing the shoppers to use the flatbed cart, Global Times reports.

In the United States, two teenage boys pleaded guilty to felony assault after they dropped a shopping cart from a fourth-story guard rail and it hit a 47-year-old mother in New York City, Fox News reports. Marion Hedges, a philanthropist, suffered brain damage from the accident-induced coma.

"She's not the same person,” a source close to Hedges told the New York Post. “Talking to her is like talking to a 9-year-old or a 90-year-old. She gets emotional and forgets things quickly.”
