Guilliams and her friend Brenden Vega were hiking through the wilderness in Santa Barbara County, California. While they were hiking, both fell and seriously injured themselves. After calling out for help for hours, Guilliams left Vega where she went to go get help. Sadly on her way out of the wilderness, Guilliams fell again, and later died where she landed.

This picture was taken the next day. At this point Guilliams was likely still alive, but she was face down in the mud with multiple broken bones. She probably heard the passing hikers, but was unable to call out to them for help. These same hikers did eventually find Vega and manage to save her life.
