It’s one of those freak occurrences that spawns unfathomable tragedy. Andrew Scott Reisse was a VR computer graphics engineer working on the Oculus Rift, a project which he helped to co-found. He was struck and killed in a crosswalk four miles away from his office at the end of a police chase in Santa Ana on Thursday. Three suspects tried to flee on foot from their Dodge Charger after Reisse was hit, but all were captured by police.

“Andrew was a brilliant computer graphics engineer, an avid photographer and hiker who loved nature, a true loyal friend, and a founding member of our close-knit Oculus family. Andrew’s contributions span far and wide in the video game industry. His code is embedded in thousands of games played by millions of people around the world. Words can not express how sorely he will be missed or how deeply our sympathy runs for his family.”
