The incident occurred in the early hours of Wednesday morning, October 23rd in Essex, southeast England. 

According to The Washington Post, the bodies were found in the trailer of a semi truck parked on the side of the road near Waterglade Industrial Park in Grays, Essex. An ambulance was called to the site, but all 39 people, 38 adults and 1 teenager, were pronounced dead on the scene.
