Harris County Sheriff's Office deputies said a Chevrolet Suburban and a Chevrolet Colorado collided after the traffic signals were out and neither driver stopped at the intersection. It should've been treated as a 4-way stop.
A three-year-old child and an eight-month-old baby were both killed in the crash, according to officials.
Two other children, ages two and four, were taken by LifeFlight to an area hospital for treatment.
Investigators said there were about a dozen or more people in the Suburban when the accident happened.
Garrett Rd. was shut down both ways, and Beltway 8 at Little York was also closed. Traffic was backed up for miles as deputies investigated the scene.
HCSO says it is still investigating. No word yet if any charges will be filed.
