The driver was arrested, and about 20 others rescued from the rig were hospitalized in very critical condition, many with extreme dehydration and heatstroke, officials said.
San Antonio Police Chief William McManus, said "We're looking at a human-trafficking crime," calling it "a horrific tragedy."One U.S. official said Sunday evening that 17 of those rescued were being treated for injuries that were considered life-threatening.
Spokeswoman for U.S. Immigration and Customs Enforcement, said Liz Johnson, said they were called to the San Antonio parking lot late Saturday or early Sunday and found eight people dead inside the truck. A ninth victim died at the hospital.
The victims "were very hot to the touch. So these people were in this trailer without any signs of any type of water," San Antonio Fire Chief Charles Hood said.The tragedy came to light after a person from the truck approached a Walmart employee in the parking lot and asked for water late Saturday night or early Sunday morning, said McManus, the local police chief. The employee gave the person water and then called police, who found the dead and the desperate inside the rig. Some of those in the truck ran into the woods, McManus said.
Investigators checked store surveillance video, which showed vehicles arriving and picking up people from the truck, authorities said. Walmart released a brief statement Sunday saying it was doing what it could to help investigators. On Sunday evening, about 100 people gathered at a San Antonio church for a vigil to mourn those killed.
Authorities would not say whether the trailer was locked when they arrived, but they said it had no working air conditioning. It was just the latest smuggling-by-truck operation to end in tragedy.
Based on initial interviews with survivors of the tragedy, more than 100 people may have been packed into the back of the 18-wheeler at one point in its journey, ICE acting Director Thomas Homan said.
Officials said 39 people were inside when rescuers arrived, and the rest were believed to have escaped or hitched rides to their next destination. Some of the survivors told authorities they were from Mexico, and four appeared to be between 10 and 17 years old.
Investigators gave no details on where the rig began its journey or where it was headed. But Homan said it was unlikely the truck was used to carry the immigrants across the border into the United States. He said people from Latin America who rely on smuggling networks typically cross the border on foot and are then picked up by a driver.
"Even though they have the driver in custody, I can guarantee you there's going to be many more people we're looking for to prosecute," Homan said.Mexican Consul General in San Antonio Reyna Torres said Mexican nationals were among the survivors and those who died on the rig. The consulate has been in contact with family members both in Mexico and the U.S., Torres said.
"The Mexican government also released a statement Sunday evening expressing its condolences to the relatives of those who died and called for an "exhaustive investigation" Guatemala's foreign ministry added that at least two Guatemalans were on the abandoned tractor-trailer.Crdt: AP.
Tekandi Paniagua, communications director for the foreign ministry, said the two male survivors told consulate officials they crossed the border by foot at Laredo and boarded the rig. They told officials their final destination was Houston.
Federal prosecutors said James Mathew Bradley Jr., 60, of Clearwater, Florida, was taken into custody and would be charged on Monday. The local U.S. Attorney's Office wouldn't say whether Bradley was the alleged driver of the truck who was arrested.The U.S. Homeland Security Department stepped in to take the lead in the investigation from San Antonio police. Department Secretary John Kelly said the incident demonstrates the brutality of smuggling organizations that "have no regard for human life and seek only profits."
