A witness reported that they had seen the brothers beat David and Brian to death outside a bar in Mio, Michigan. Others reported that the Duvalls bragged about feeding the remains of David and Brian to their pigs. The witness did not come forward until 2003 due to fear from the brothers. Both were convicted of first degree murder and sentenced to life in prison. Neither David nor Brian's remains have ever been found.
