Incident
The crash happened on the southbound side of Loop 303 near Northern Avenue. DPS confirmed that multiple vehicles were involved in the incident, though officials have not identified the vehicles or explained how the crash unfolded.

Investigators are continuing to examine the circumstances surrounding the incident. At this time, officials have not confirmed whether factors such as speed, impairment, or driver distraction contributed to the crash.
