Leonard Ennis

Leonard Ennis is a now-incarcerated, prolific serial killer who appeared in Season Eleven of Criminal Minds.

Background
Little is known about Ennis's personal life, other than he ran away from home one summer. Sometime afterwards, he met a teenage girl named Suzy Johnson and killed her. He then repeated the process with thirteen other girls (though he implies there could be more) before being caught by authorities and imprisoned in Virginia. Sometime in or before 2015, Ennis became the subject of several interviews with Doctor Tara Lewis, a forensic psychologist with the FBI.

The Night Watch
At the beginning of the episode, Ennis has another interview with Lewis; in this one, he recounts the time he ran away from home and encountered Suzy Johnson. When she asks him what he felt when he was killing Suzy, he replies that he doesn't know. Lewis denies that and explains that something drove him to continue killing, but Ennis continues to insist that he doesn't know and says that it was just something he did, as "people do things every day".

At the end of the episode, after Lewis finishes up a case with the BAU, she attends another interview, which was rescheduled to an earlier date by Ennis. When she asks why, he taunts her that he is actually the one interviewing her and not the other way around. He then asks about her fiancé, and when Lewis replies that he left, Ennis assumes that she had to choose between the both of them. However, Lewis retorts that she chose herself and continues with the interview.

The Storm
He reappeared in the episode.

Modus Operandi
Ennis was described as targeting teenage girls as his victims. Aside from that, other details about his M.O. were not disclosed.
