[HIGHLIGHTS] A plot and a second shooter: the Prosecutor's Office demolishes the theory that Mario Aburto acted alone to murder Luis Donaldo Colosio

Luis Donaldo Colosio was shot twice in the head and abdomen in 1994. Mario Aburto, a 23-year-old PRI worker, claimed he fired the shots, but later said he was tortured to incriminate himself and falsify information.

The Attorney General's Office (FGR) has taken a step in a direction that dismantles the theory that Abur to was a solitary murderer. The Prosecutor's Office has also implicated Genaro García Luna in the case.
