Officers responded to the parking lot of TJ Maxx in Hanover where they found Keith Russell, 42, and Kelsy Russell, 31, locked out of their vehicle on August 13, police said.
While attempting to unlock the vehicle, officers saw an unspecified controlled dangerous substance in clear view, police said.
The car then started to roll forward because it had been left in drive, police said.
The couple, of Bushkill, PA, were arrested and taken to headquarters, where a search of the vehicle turned up around $135,000 in cash, police said.
Both were charged with money laundering, possession with intent to distribute, two counts of possession of CDS, possession of prescription legend drugs, drug paraphernalia and hypodermic needles, police said.
Keith Russell was also issued motor vehicle summonses for unregistered vehicle, driving under the influence, careless driving and possession of CDS in a motor vehicle.
Both were transported to the county jail pending an appearance in court.
