A Pharr man and his 4-year-old son died in a Monday morning crash involving four vehicles near Edinburg, according to the Texas Department of Public Safety.

The crash happened at around 2:38 a.m. Monday on US 281 south of FM 1017 north of Edinburg in Hidalgo County.

According to a DPS news release, the crash happened when a suspected intoxicated male driver of a white Chevrolet Malibu was traveling northbound on US 281 on a southbound lane. 

In the release, DPS noted that beer cans were found inside the vehicle.

A white Chevrolet Colorado traveling southbound on US 281 veered off the roadway to avoid colliding with the Chevrolet Malibu and, as a result, lost control and rolled over, stopping on the southbound frontage road.  

The Chevrolet Malibu then collided with a black Hyundai Tucson traveling southbound on US 281 that was occupied 32-year-old Mark Anthony Alvarez and his son, identified as John Andrew Escamilla.

The collision caused the Hyundai to spin across the southbound lanes and crash into a white Freightliner tractor-trailer traveling southbound on US 281, DPS said.

Alvarez succumbed to his injuries at the scene, while his son — who was unsecured in the vehicle — died at the hospital, DPS said.

The occupants of the Chevrolet Colorado, a woman and a child, were hospitalized in stable condition. 

The driver of the Chevrolet Malibu was hospitalized in critical condition, and he is suspected of being intoxicated pending his blood work results, DPS said.
