"Preliminary investigation indicates a John Deere backhoe was traveling southwest on Chapel Hill Court with multiple children and adults riding on various moving parts of the backhoe," a spokesperson for the Texas Department of Public Safety told the publication.
"While in motion, the driver of the backhoe operated equipment causing the front bucket to dump, and occupants riding in the bucket fell to the ground."
Two more children and an adult were taken to local trauma centers with injuries. Chauhan himself was not hurt.
As well as two counts of second-degree manslaughter, Chauhan also faces three counts of endangering a child, and one count of aggravated assault with a deadly weapon.
