On the morning of March 16, 2015, the night-shift nurses of Martin Correctional Institution clustered in the medical exam room to brief Robert Silvis, the prison’s nursing director. Silvis had just started his shift at the facility in Indiantown, Florida, and the nurses looked stunned. They explained, as well as they could, what had occurred the night before.
A man was dead.
Silvis called a prison captain and pulled the surveillance tape.
The video showed someone Silvis recognized as Carolyn Conrad, a licensed practical nurse, entering the D block dormitory at 7:24 p.m. to begin the nightly ritual of distributing medication to the men. When a corrections officer arrived outside cell D2210, he discovered Christopher Cox sprawled on his stomach on the concrete floor. Cox was unresponsive, his arms slack against his sides, his face bloodied and pressed against a pillow, a white T-shirt twisted into a noose around his neck.
