Ellen Rios

Ellen Rios was a deputy of Sheriff Vaines and a member of the search party in Part 2. She, unlike Vaines, doesn't suspect Sarah for the other women's disappearances. During the time in the caves, she and Sarah grow closer (a reference to the friendships tearing apart in Part 1), with Sarah helping her to survive. In the final chamber before the exit, Sarah remembers Rios has a daughter and realises that she has nothing left to live for, so she distracts the large group of Crawlers and sacrifices herself so Rios can escape. Rios does so, and runs away for a bit before using her phone. Afterward, she turns around to be hit in the face by a shovel, wielded by the local man who saved Sarah at the beginning.He apparently knows of the crawlers, as he drags her unconscious body back to the entrance, and as she is about to come around, a Crawler pops out of the hole, possibly killing Rios.
