BELTON, Mo. (AP) — Court documents indicate a 54-year-old man who was shot by Belton police over the weekend had threatened to kill his mother. Cass County prosecutors say police shot William Mallow early Sunday when he advanced on them with a machete. Mallow is charged with two counts of first-degree assault or attempted assault. Court documents indicated Mallow called police to say he was going to kill his mother but when officers arrived the woman was safe inside. Two officers went inside and confronted Mallow, who allegedly ignored commands to drop the machete and advanced toward the officers. Mallow was seriously injured and remained hospitalized Tuesday.
