ST. LOUIS (AP) — A homeless man was found guilty of attacking four other homeless people with a hammer and handrail in St. Louis in a fight over snacks and water.

The St. Louis Post-Dispatch reports 62-year-old Edward Moore was convicted Friday on four counts each of first-degree assault and armed criminal action.

Authorities said Moore attacked two homeless men and two homeless women in July 2017 inside a vacant school where homeless people regularly slept.

Moore was accused of beating them with a ball peen hammer and a roughly 4-foot-long section of a wooden handrail with two wall brackets still attached.

Police and testimony indicated Moore believed the victims had ransacked his belongings and stolen food.

Two of the victims were critically injured but survived. The other two were less seriously hurt.
