It took place at the Home Furniture Class showroom when Siripun Kaysoong-nern led two customers, including a heavily pregnant woman, up in the lift.
While ascending, the lift suddenly started dropping from the fourth floor, possibly because a sling chain snapped.
All three people in the elevator sustained critical injuries. Prapawarin Jaidee had a miscarriage and is under intensive care at the Maharaj Nakhon Ratchasima Hospital. The other customer, Kris Chuaychua, is stable but is still in hospital.
Police have not yet pressed charges pending examination of evidence. The investigation will determine whether the accident resulted from recklessness.
