Police in Cleveland say a man shot and killed another man Sunday while broadcasting it on Facebook Live. Authorities are looking for Steve Stephens, who is considered armed and dangerous, reports CNN. Stephens not only allegedly broadcast the killing, he posted another video in which he claimed to have "snapped" and killed other people, too, reports Cleveland.com. Authorities have not verified whether those claims of additional victims are true, per a police statement that describes Stephens as a 6-foot-1, 244-pound black male with a full beard.
