TIJUANA - Hundreds of anxious families waited outside Tijuana's infamous La Mesa State Penitentiary for word on their loved ones yesterday after police fatally shot 19 prisoners to regain control of the facility. Wednesday's riot was the second deadly melee in three days at the prison just across the US border from San Diego. State authorities blamed prison troublemakers for the uprisings that killed a total of 23 inmates, but relatives of the inmates say they rioted because they were not given food or water since the riot on Sunday (AP)."
