What We Know (and Don’t Know) About Female Psychopaths

On Memorial Day, Investigation Discovery will air a two-part series about Kelly Marie Cochran, who is serving a life sentence for killing her lover in 2014 and her husband in 2016. I first became aware of this case two years ago, when allegations that she might be a female serial killer began surfaced. Her brother, Colton Gaboyan, thinks she is responsible for as many as nine victims. To date, she has not been charged with any other murders, so we don’t know whether those allegations are true.
