USA: student killed in Ny, arrested a thirteen year old

A 13-year-old boy, Zyairr Davis, and two others aged 14 would be the authors of the murder of Tessa Majors, the Barnard College student killed in Morningside Park, a short walk from Columbia University in New York. A death that shakes the students and the whole Big Apple for its violence in an area that is always monitored and in a park that, after having been considered dangerous for years, had recently regained an excellent reputation.
It is not only the killing of the student that is shaken, but also the age of the authors, all of them minors and for whom one wonders about the entity of the sentence. For now, the only one arrested is a thirteen year old from Harlem, who has, however, discharged the responsibility on two of his friends: the boy has in fact told the police that he witnessed the attack and the robbery and that he was present when one of his friends has stabbed the girl.
According to preliminary reconstructions, the three kids were at the park when they pointed a man they had started to follow. Later, however, they spotted Majors, and decided that she would be their prey. They blocked her, immobilized her with a move as if to strangle her and stole what she had in her pocket. The girl resisted and one of the three kids took out the knife and hit her. In addition to the 13-year-old arrested, another suspect is currently in police custody, for whom formal charges have not yet been advanced. Investigators continue to examine the crime scene, sifting through the sub with the park's pond.
