HURST, Texas (CBSDFW.COM) — A wrong-way driver struck three vehicles Thursday morning, killing a teen and a dog.

Around 5:15 a.m. Nov. 28, a black Chevy Tahoe entered the Boulevard 26 exit ramp — driving into oncoming eastbound 820 traffic and hitting two dark-colored SUVs and a light-colored sedan.

The driver of the Chevy Tahoe — who has not been identified at this time — was transported to the hospital in stable condition.

However, the driver of the light-colored sedan — identified as 17-year-old Benjamin Castaneda — was transported to the hospital in critical condition. A dog that was also in the vehicle died as well.

A third driver was also transported in stable condition, and the fourth vehicle involved did not receive any major injuries.

This is an ongoing investigation.
