Serena Williams: Patenema Ouedraogo used Serena Williams’ Twitter feed to keep track of the tennis star and popped up everywhere Williams was. He was finally apprehended when he was caught red-handed breaking into the athlete’s home. Williams is no stranger to stalkers. German fan Albrecht Stromeyer was ordered to stay at least 1,000 yards away from the tennis great after he pleaded guilty to stalking.
