A man who got into an argument with his estranged wife and her family over his children was arrested Sunday in a house-to-house shooting rampage in rural Mississippi that left eight people dead, including his mother-in-law and a sheriff’s deputy. The gunfire erupted on Saturday night at Godbolt’s in-laws’ home in Bogue Chitto after the deputy arrived in response to a domestic disturbance call, and spread to two houses in nearby Brookhaven, about 70 miles south of Jackson.
