Eight people were found dead in the back of a tractor-trailer parked at a Walmart lot in San Antonio, authorities said early Sunday, reported CNN.
San Antonio Police Chief William McManus said they discovered the bodies after a phone call late Saturday.
"We got a call from a Walmart employee about a welfare check in a tractor-trailer that was parked on the lot here," McManus said at a news conference.
"He was approached by someone from that truck, who was asking for water. Came back with a water, called the police and we arrived on scene and found eight people dead in the back of that trailer."
