Colombian army soldier Sebastián Villegas allegedly threatened to kill his model girlfriend Isabella Mesa in December, four weeks before he stabbed her dead in his home.
Isabella Mesa, 19, met Sebastian Villegas, 21, online more than a year ago. He is accused of stabbing the young mother to death after people witnessed them getting into a heated argument.
Colombian prosecutors said Isabella Mesa was living in Mexico and returned to Medellín to spend time with her soldier boyfriend, Sebastián Villegas, who allegedly killed her.
