On Sunday, Sept. 6 at approximately 1 p.m., San Marcos Police, San Marcos Fire and Hays County EMS responded to a fatal multi-vehicle collision on W. Wonder World Drive and Purgatory Creek Bridge.
According to evidence at the scene and witness statements, a silver 2011 Ford F250 driven by Kyle Nissen, 30, of San Marcos was driving westbound on W. Wonder World in the left lane when he drifted to the right and side-swiped a Grey Nissan Rogue. The Ford F250 then drifted back to the left and crossed the center double-yellow stripe and ultimately struck four other vehicles head-on including a white 2020 Ford F150, a black Chevrolet Silverado, a Grey 2018 Mazda CX9, and a White 2012 Nissan Altima.
David Hollinbeck, 61, of San Antonio, the driver of white 2020 Ford F150, was killed in the collision. His passenger and wife, Toni Hollinbeck, was transported to Seton Hays and later released the same day.
Other than the driver of the side-struck Nissan Rogue, every driver and passenger in the vehicles involved was transported to Ascension Seton Hays Hospital in Kyle, several with serious, but not life-threatening injuries.
The roadway was shut down between Craddock Ave and Hunter Road until 6:30 p.m. so the San Marcos Collision Investigation Team could investigate. Texas State University Police and San Marcos Park Rangers assisted in shutting down the roadway until barricades were erected. The Hays County Citizen Emergency Response Team (CERT) responded and assisted with shade and hydration for investigators.
The Collision Investigation Team is investigating and believe that alcohol was a factor in the accident. A blood search warrant was obtained for Nissen. Pending the results of Nissen’s toxicology, additional warrants may be forthcoming.
This is the 13th traffic fatality of 2020. As of this incident, San Marcos has experienced the highest number of traffic fatalities in a single year since 2012 when the City counted 13 fatalities total for the year.
