San Luis Obispo County Sheriff's deputies said they arrested two people in Arroyo Grande this week on drugs and weapons charges following a months-long investigation.
Investigators said they arrested Kent Lawson, 35 of Nipomo, in June for being a felon in possession of a firearm and possession of narcotics for sale.
After Lawson posted bail, detectives launched an investigation and said they learned he was still selling drugs.
On Monday, they served a search warrant at Lawson's residence in the 200 block of Trevino Drive in Nipomo, while he was simultaneously pulled over and arrested in Arroyo Grande.
Amanda Zeller, 37 of Nipomo and who was in a separate vehicle, was detained, as well.
During the searches of Lawson, Zeller and Lawson's residence, investigators said they found four ounces of suspected methamphetamine with a street value of $4,000, a small quantity of fentanyl, a sawed-off pump action shotgun, a starter pistol resembling a revolver, ammunition for the shotgun, and items associated with drug sales.
Lawson was arrested on charges of being a felon in possession of a firearm, possession of narcotics for sale, committing a felony offense while out on bail, possessing a controlled substance and driving with a suspended or revoked license.
Zeller was arrested on two local felony warrants.
Both Lawson and Zeller remain in custody in the SLO County Jail.
