During testimony Wednesday, police officers and Department of Homeland Security investigators described the events of April 1, 2014, which included surveillance in an Aurora laundromat parking lot, a traffic stop on Chicago's North Side and the discovery of a makeshift loft inside Alarcon's garage. Members of the Aurora police special operations group, along with others involved in a Department of Homeland Security drug task force, collectively explained suspicions about an exchange between occupants of a Jeep and Saturn near Grove and Ohio streets in Aurora which prompted the Jeep to be followed into Chicago. The Jeep was stopped and a search uncovered a hidden compartment filled with $190,000 in bundles of $10,000.
