The fight against Escobar ended on December 2, 1993. The police used radio triangulation technology to find Escobar. The United States provided this technology to a Colombian electronic surveillance team. The group was led by Brigadier Hugo Martinez. The team found him hiding in a middle-class barrio in Medellín. With the permission from authorities, a firefight with Escobar and his bodyguard, Alvaro de Jesús Agudelo AKA "El Limón", happened. They tried to escape by running across the roofs of nearby houses to reach a back street, but both were shot and killed by Colombian National Police. Escobar suffered gunshots to the leg, torso, and the fatal one in his ear. It is not known who actually fired the final shot into Escobar's head. It is also unknown whether this shot was made during the gunfight or as part of possible execution. There is wide speculation about this. Some of the family members believe that Escobar could have committed suicide. His two brothers, Roberto Escobar and Fernando Sánchez Arellano, believe that he shot himself through the ears. "He committed suicide, he did not get killed. During all the years they went after him, he would say to me every day that if he was really cornered without a way out, he would shoot himself through the ears." The autopsy showed that there was no stippling pattern found around the ear, which suggested that the shot which killed Escobar was fired from further than an arm's length away.
