William Jose Guerrera Castillo is suspected of driving the two young biology students to the place where they were killed by members of the drug gang “Los Urabeños,” according to police and the Prosecutor General.
Castillo was transferred to Monteria, where he will stand trial.
He is the fourth suspect arrested in connection with the case.
The violence was attributed to rival neo-paramilitary and drug gangs such as Los Urabeños, “Los Paisas” and “Los Rastrojos” vying for power in the region.
The ringleader of Los Urabeños, Roberto Vargas Gutierrez, alias “Gavilan,” is suspected of the murder of the two biology students.
