Sixteen year old Miguel Ángel Castellanos Marín was a ninth grade student and member of the Casa Morada Cultural Collective in Medellin, Antioquia.
Miguel Ángel was a member of a group working to promote cultural activities for young people and was also involved in the local community radio station.
On 8 February 2020, he disappeared in the Belén neighbourhood and two weeks later his body was found in the Medellín river with signs of torture.
It is believed that the motive for the killing was that somehow he had crossed an invisible line in the territorial dispute between armed criminal groups who are fighting for dominance in the city.
