Oct 28(AP/UNB) -- A bullet hole fragments the window of a building, from a recent shootout in Culiacan, Mexico, Saturday, Oct. 26, 2019. The physical scars of the Oct. 17 gunbattles _ what’s come to be known as “black Thursday” by residents of Culiacan, the capital of Sinaloa and a stronghold of the Sinaloa cartel long led by Joaquín “El Chapo” Guzmán _ are beginning to heal, but residents are still coming to grips with the worst cartel violence in recent memory.
