This Mexican border city 15 miles south of downtown San Diego has long been one of Mexico’s most violent cities. But even by murder-capital standards, Tijuana has an extremely high murder rate, with no signs of the killings abating. Already, 2019 kicked off with three murders on New Year’s Eve. The city’s homicide rate jumped from roughly 100 murders per 100,000 residents in 2017 to 138 per 100,000 in 2018.
