SAN MARCOS, Texas (KXAN) — San Marcos police have identified the victims of a fatal crash that closed a portion of southbound Interstate Highway 35 in San Marcos Thursday morning.

Police say 29-year-old Orlando Valdez and 21-year-old Dana Watson were driving home from an event in Austin around 2:45 a.m. when they were rear-ended by a dump truck.

Valdez was pronounced dead at the scene and Watson was taken to the Central Texas Medical Center to be treated for her injuries. She was pronounced deceased soon after.

The driver of the truck suffered minor injuries and was taken to Ascension Seton Hospital in Kyle for treatment.

Investigators say Valdez was either stopped or driving slowly in the far right lane when the dump truck collided with his vehicle.

The 204B exit was shut down for several hours as crews worked to clear the scene. I35 southbound was also closed for about an hour.

The crash is being investigated by the Collision Investigation Team of the San Marcos Police Department.

Valdez and Watson’s deaths are the ninth and 10th traffic fatalities in San Marcos in 2019.
