A 19-year-old student from Austin was killed in a crash along RM 12 near San Marcos early Sunday morning.

A Department of Public Safety spokesperson said a 23-year-old Irving man was traveling southeast on RM 12 around 2:20 a.m. Oct. 30. The man said he did not observe a group of young adults walking on the 4000 block of RM 12 and struck two pedestrians.

One of the pedestrians, Luis Alvarez, died at the scene. The second student, also 19 and from Austin, was treated for his injuries and released.

DPS said the driver stopped after the crash and called 911 before providing first aid.
