The Department of Public Safety says it's working with the district attorney's office on exactly what those charges will be. The big rig driver reportedly slammed in a vehicle driven by the Prill family on 290 near the Grand Parkway.
Nine-year-old Zachary Prill was killed. His mother and 8-year-old sister were seriously hurt and are still in the hospital.
Several other people were also injured in the chain reaction crash.
The father told troopers they had just dropped him off at a church in Hockley so he could help with Easter preparations. The mother and two children were going to run errands and then pick him back up.
Zachary was a student in the Cy Fair ISD. The district released a statement Sunday, which said, "The entire Ault community is saddened by the death of one of our students. Our thoughts and prayers are with his family, classmates, friends and all who knew him. Additional counselors and support staff will be on campus as long as necessary to assist students and staff during this difficult time."
