On the last day of Adam Collier’s life, he had breakfast in his cell in Kern Valley State Prison. He wrote two letters, one to his mother, the other to the guard who would later find his body.

During the previous four years in prison, Collier had been hospitalized for mental health crises 14 times. His many letters to family and friends wobbled between lucidity and gibberish. His medical records proffered graphic descriptions of self-harm. Collier had originally landed in prison for exposing himself to women in public while high on meth.
