 Also charged is 18-year-old Lamar Thomas, who's alleged to have shot Ewing from a second train door. Ewing's cousin, who was on the train, said the men recognized the victim as a rival gang member, and at least one of the assailants fired a gun that was illegally modified to be fully automatic. The killing was recorded on surveillance video. Authorities issued an arrest warrant for Thomas. The Jennings brothers are in custody. I'm Matt Sepik, St. Paul. This is NPR News.
