A 25-year-old man has been charged with murder for randomly stabbing a woman in her 70s in a South Florida neighborhood. The attack occurred in the Southwood neighborhood in Stuart. Neighbors had reported a suspicious man going door to door and asking unusual questions before the attack. A deputy found the suspect "actively stabbing" the victim, while a Good Samaritan intervened. The victim was transported to the Cleveland Clinic Martin South, where she died of stab wounds. No connection between the suspect and the victim has been identified.
