Investigators with the Pearl River County Sheriff’s Department on a surveillance operation witnessed what appeared to be drug activity and netted a suspect in a subsequent traffic stop.

Lt. Donnie Saucier, an investigator with the department, said that while investigators were on a surveillance operation Tuesday on South Abrams Avenue in Picayune they observed a man enter a house at another location. The suspect stayed in the house for a short time and then left. The suspect’s actions were allegedly indicative of a drug transaction, Saucier said.

The investigators followed the suspect and saw him allegedly run a stop sign, Saucier said. A traffic stop on the vehicle identified the suspect as Ralph Wayne Davis, 43, of Sid Crawford Rd., Pearl River, La.

After receiving consent to search the vehicle, the investigators found about 152 Percocet pills, which is schedule II narcotic, Saucier said.

“If you have a prescription for a medication and decide to sell that medication, we’ll consider you a drug dealer,” Saucier said.

Since Davis did not have a prescription for the medication he was in possession of it, he was charged with possession of a controlled substance with intent to distribute. The incident is still under investigation.
