BUTLER, Pa. (AP) — Police in Pennsylvania say a 70-year-old man wearing a rubbery Halloween mask and brandishing a rusty hatchet attacked his neighbor while he mowed the lawn. Penn Township police Cpl. Jack Ripper tells WPXI-TV that Ronald Postreich attacked his 70-year-old neighbor Wednesday night after years of feuding. Ripper says the two have been arguing for a long time over their rural properties near Butler, but this was the first time it turned violent.
