Edwin Alexis Guerrero, 36, was fatally shot on November 22, 2016, in the parking lot of a Wendy’s on West Broad Street in Columbus, Ohio. He was taken to Mt. Carmel West Hospital, where he died of his injuries.

Police say the shooting followed an altercation between Guerrero and two teenagers, Nigel L. Jackson, 17, and Taysen R. Hixon, 15. Witnesses reportedly told investigators that Guerrero pulled out a gun and fired at Jackson and Hixon, who returned fire. Jackson and Hixon were arrested and charged with murder, but a Franklin County grand jury later declined to indict, finding evidence consistent with the teens’ claim of self-defense, and no charges were filed.

The circumstances in the parking lot, the contrasting accounts of who fired first, and the grand jury decision leave difficult questions about what happened that night.
