No charges will be filed in the deaths of two men who were shot at a tailgating site after a Detroit Lions game. Prosecutor Kym Worthy says it's a case of self-defense. She also disclosed the extraordinary fact that one bullet killed both men Sunday. Worthy says the 40-year-old shooter felt threatened when 25-year-old Jalen Welch pulled out a gun during an argument. The shooter fired once and the bullet killed Welch and 40-year-old Rayshawn Palmer. The prosecutor says Palmer was just trying to be a peacemaker.
