Federal prosecutors are seeking the death penalty for a St. Louis man accused of killing nine people since 2008 during his involvement in a drug trafficking ring. Prosecutors say he killed three people in 2008, two in 2010, three in 2013 and one man in 2014. Several of the victims were killed while inside vehicles or in drive-by shootings. One woman, a grandmother of eight, died when she was hit by a stray bullet while looking out her apartment window.
