Police say a husband and wife are behind bars after conspiring to rob a Walmart pharmacy.

Officials arrested Gregory Dalrymple last week and took his wife Lindsey into custody Tuesday.

Police say Lindsey drove Gregory to the Walmart in Lower Nazareth Township, Northampton County, back in August and gave him a gun he used to hold up the pharmacy.

Police say the two were addicted to Fentanyl.

They're both locked up in Northampton County Prison.
