The individuals are suspects in two murders and two attempted murders, all in Los Guidos en Desamparados. Raids Wednesday were in San Sebastián and Higuito de Desamparados.
The double murder took place June 12 in Los Guidos. Agents suspect the men were killed because they had robbed the woman who was detained Wednesday.
The attempted murders were Aug. 30 when two men were fired upon and wounded in the same area, said agents.
Agents also found bulletproof vests, police-type radios, a shotgun, pistols and various types of ammunition at the scenes of the arrests, they said.
