Colombian soldier, 21, 'threatened to kill his glamorous girlfriend, 19, a month before she was found dead and stuffed in a SUITCASE'

Colombian army soldier Sebastián Villegas allegedly threatened to kill his model girlfriend Isabella Mesa nearly one month before he stabbed her 24 times and stuffed her dead body inside a suitcase at his home, court documents reveal.

'If she talked to other men, he wouldn't mind killing whoever it was, he would even kill her himself,' a judge said while reading testimony from the victim's mother, Sandra Mesa, during a hearing Wednesday. 'She heard those words in the middle of a video call on December 30, 2023. 

Isabella Mesa, 19, was found dead by Villegas' mother in one of the rooms of their Medellín residence on Sunday night, several hours after the couple had attended a party at a farm and got into a heated argument.

The young mother had traveled to Colombia from Mexico, where she lived with her mother Sandra Mesa and her three-year-old son, to spend time with Villegas, who was on vacation.

The judge overseeing an arraignment hearing Wednesday read testimony from Sandra Mesa, who said her daughter initially met Villegas when she was 13 years old living in her hometown of Copacabana, 25 miles outside Medellín.

Isabella, who moved to Mexico to pursue a career in modeling, would spend the majority of her days chatting on her cellphone with Villegas, her mother told investigators.

'Day and night she was stuck talking on the cell phone. However, sometimes she heard loud conversations or video calls and she could notice that he was threatening her,' the court document indicated. 'He demanded that she share the screen and send WhatsApp videos to see who she was talking to. She saw that Sebastián was a jealous person.'

Villegas' increased state of jealousy rose to the point where he threatened to murder Isabella Mesa four weeks before he took her life.

'He was sick with jealousy, her daughter sent everything he asked of her and then he asked her for forgiveness," the court document revealed.

The judge said that Villegas stabbed Isabella eight times in the neck and stabbed her seven times around the left breast.
