Detective Mader decided to follow up on the tip, obtaining further information that an "L. Gates" had purchased an airline ticket leaving from Chicago's O'Hare Airport and arriving in West Palm Beach, Florida. Working with the DEA, Mader was able to ascertain that Gates had boarded the plane and arrived in West Palm Beach. The DEA surveillance team determined that Gates had met a woman at a Holiday Inn room registered to Susan Gates and that the couple had gotten into a car together driving toward the Chicago area. They estimated the pair due back in Bloomingdale within 22 to 24 hours.
