Man sentenced to 13 years in prison for stabbing his ex-girlfriend's current partner to death in MA

The crime took place on October 23, 2025, in the village of Vaca Morta, in the rural area of ​​the municipality. According to the complaint, the murder was motivated by jealousy after the end of Tailson's relationship with the woman.

According to investigations, Tailson and the woman had a brief relationship, but she decided to end it. The man, however, did not accept the end of the relationship.

On the night of the crime, the woman was at home, drinking alcoholic drinks with her sister and another person, when Tailson arrived at the scene. Even without being invited, he remained at the residence, where he drank and smoked crack.

Afterwards, Sebastião arrived at the house and greeted everyone, including Tailson. A few hours later, the accused left.

During the early hours of the morning, Tailson sent a message to his ex-girlfriend saying he was on his way home. He stated that he knew that she and Sebastião were together. To avoid an argument, the woman said that Sebastião was not in the house. Even so, Tailson went to the location, jumped over the side wall and entered the residence.

He then took a knife from the kitchen and went to the bedroom, where his ex-girlfriend was with Sebastião. According to the complaint, he tried to hit the woman, but failed. Then, he struck Sebastião in the chest and fled.

The woman called an ambulance, but Sebastião died before reaching the hospital. The Maranhão Military Police (PM-MA) was called and began searching for the suspect. In the early hours of the following day, Tailson surrendered to the police. He was taken to Central Duty, but remained silent during the interrogation.
