At around 1 p.m., the wreckage of his car and Stillwell’s dead body were found at the Devil’s Backbone ridge in San Marcos, Texas. Police Chief Howard Williams said, “We’re not sure exactly whether the collision killed him or if he shot himself.” Though Williams told reporters it was clear that Stillwell had died from “self-inflicted injuries.”

Chief Williams told reporters: “Saying more than I probably should, I don’t believe this was a rise of sudden passion. I believe this was planned.” The University Star reports that Stillwell was “controlling” of Nicholls. One friend of Nicholls, Sarah Wolfshohl, told The Daily Mail that Nicholls had been looking for a way out of the relationship for a while. Wolfshohl said, “I never thought he was capable of taking it to that point.” She added that at times Stillwell wouldn’t let Nicholls go out.”

Stillwell also knew Robledo previously, as all three worked together at a local Chipotle restaurant.
