Date: August 6, 1998
Details: On August 6, 1998, Chom Ping Thammavong was driving his wife and their four children to Wisconsin from Bakersfield, California. He was driving a Toyota 4-Runner with a U-Haul trailer attached. At 2AM, he was traveling east on I-40 near the Arizona/New Mexico border. There were few cars on the road; Chom Ping was driving in the fast lane. Suddenly, he looked in the rear-view mirror and noticed two trucks quickly approaching him. He moved over to the slow lane to avoid them. Without warning, one of the trucks slammed into the back of the U-Haul, causing the vehicle to go out of control.
The 4-Runner flipped over and the two youngest children, Chansamai, nine, and Abby, six, were thrown out the windows and killed. The other family members survived but were seriously injured. Police have been unable to locate the driver of either truck. The only evidence left behind were pieces of the truck's bumper that were found strewn across the highway.
Suspects: The suspect's vehicle was a blue/white GMC.
