A tractor trailer and a van crashed on a highway in the northern Mexican state of Tamaulipas on Sunday, killing 26 people, local authorities said according to Reuters.
The two vehicles crashed about half an hour outside of the state capital Ciudad Victoria and then caught on fire, the Tamaulipas' public security ministry said.
Once authorities arrived at the site of the crash, they found the truck carrying the trailer was no longer at the scene.
A source at the Tamaulipas prosecutors' office said investigators were unsure whether the driver of the truck had fled or if he was also killed in the crash.
