Four vehicles were involved in the crash around 2:18 a.m.; one Hyundai, and three trucks with tractor trailers. DPS says Alan Eduardo Dieguez, an off-duty officer with the El Paso Police Department, was driving a Hyundai around 100 mph when he collided with an 18-wheeler. The Hyundai veered into a ditch causing a second truck to swerve to miss debris in the road. The second truck lost control and skidded into the northbound lanes before catching on fire. The third truck hit the debris in the road and also caught on fire.

DPS troopers shut down the northbound lanes of I-35 in northern Williamson County around mile marker 277 and 275 early Tuesday morning. All main lanes reopened by 11:30 a.m. but the northbound frontage road is still blocked.

Three people were transported to the Williamson County Seton. One person died at the scene, it is not known which vehicle the person was in.

Authorities say Dieguez is charged with driving while intoxicated and unlawful carrying of a weapon .He was released from jail the same day after posting his bond. El Paso police say Dieguez has been with the department for three years. He will be placed on administrative leave once he returns to El Paso.
