A man serving life in prison for killing five family members in their Broken Arrow home in 2015 has been given three additional life sentences for attacking prison staff last July.
A Cleveland County judge ordered now-24-year-old Robert Bever to serve three concurrent life sentences that will run consecutively to his six previously life sentences. Bever pleaded guilty in August to charges of assault and battery and possessing a weapon in prison after attacking staff with an 8-inch long sharpened instrument.
Bever and his younger brother Michael were convicted in 2018 of killing their parents and three of their siblings in an attack they plotted for at least a year.
Two surviving children were adopted by a Tulsa family, and the Bever family home in Broken Arrow was torn down.
