Eight people have been found dead in a tractor-trailer outside a Walmart in Texas in what police are calling a human trafficking case.
Several other people have been taken to hospitals.
San Antonio police said a Walmart employee was approached in a parking lot by a person from the truck who was asking for water late on Saturday night or early on Sunday morning. Police said the employee gave the person the water and then called the authorities. When they arrived they found the eight people dead in the back of the trailer.
