The deputy asked the couple if he could search the truck, but he was denied.
"During this time, reasonable, articulable suspicion was obtained that criminal activity was afoot", the deputy wrote in the report.
Sheriff Terry Wagner said the couple was found in a auto with $18,000 cash and a duffel bag with marijuana residue on it.
"It's my understanding that they were stopped, in the same vehicle we caught them in, again on Interstate 80", Vrbka said.
Deputies detected trace amounts of cannabis during field tests of the money and found an over-sized garbage bag in the back of the truck containing raw marijuana residue, the report said.
About $18,000 in cash, allegedly tainted by pot, was found in their vehicle, a 2016 Toyota pickup.
County Judge John Freudenberg ordered Barbara Jiron to return to court on February 1 on the drug money charge after appointing an attorney for her. The York County Sheriff's Office said the estimated value of the marijuana was $336,000.
They also said they found "owe notes" relating to the sales of narcotics. Their 42-year-old daughter, a resident of Vermont, was driving the vehicle, but was not arrested. They reportedly told police they were on their way to Vermont with the goal of distributing the drugs as Christmas gifts and they didn't know it was illegal to transport marijuana through the state.
Patrick Jiron was driving then, and authorities stopped him for going over the center line and failing to signal.
Patrick Jiron, 80, and his wife, Barbara Jiron, 70, were each released from the Lancaster County jail on $2,500 bond Tuesday afternoon.
The couple told York County sheriff's officials that they planned to make stops in Boston and Vermont to distribute the marijuana to family and friends as Christmas gifts.
Wednesday in court the Jirons of California heard new charges after their Tuesday morning arrest.
