Michael Bever

On July 22, 2015, five members of the Bever family were murdered in Broken Arrow, Oklahoma.[2] Two members of the family, 2-year-old Autumn and 13-year-old Crystal survived. Daniel Bever, 12, called 9-1-1, saving two of his sisters' lives by alerting authorities. Crystal, one of the two survivors, identified two of her older brothers, 18-year-old Robert Bever and 16-year-old Michael Bever, as the assailants. The two older Bever brothers were subsequently arrested and charged with five counts of first-degree murder and one count of assault and battery with intent to murder.[1][3][4][5]
