His apprehension followed a routine traffic stop, where he was found driving without a license. Officials emphasized that his capture demonstrates ongoing efforts to target dangerous criminals and highlighted the importance of cooperation between state and federal agencies. Lazo-Quintanilla is identified as a member of the 18th Street Gang, a group known for violent activities across Central America.
