A major contraband investigation has led to the seizure of nearly a kilogram of methamphetamine and multiple cell phones from a Georgia prison inmate’s cell, according to authorities.

The Cherokee County Sheriff’s Office in North Carolina announced that investigators uncovered the contraband while assisting with an ongoing drug investigation that began June 1. Investigators executed a search warrant at the home of Amanda King, where a trafficking quantity of methamphetamine was reportedly seized and two people were arrested.

As the investigation continued, detectives discovered that King had allegedly been communicating through jail phone calls with inmate Rudy Cameron Lee, 34, who is currently serving a sentence for voluntary manslaughter.

Authorities said investigators learned Lee was allegedly using a cell phone while incarcerated and contacted the Union County Sheriff’s Office and the Georgia Department of Corrections for assistance. A subsequent search of Lee’s prison cell uncovered a large cache of contraband.

According to investigators, officers seized seven cell phones, a mobile hotspot device, 948 grams of methamphetamine, 2,210 grams of marijuana, 3,245 grams of tobacco, a digital scale, earbuds, Allen keys, charging cables and other accessories.

Officials said Lee’s projected release date on his current sentence is around 2038. Additional charges related to the contraband seizure are still being evaluated.

The case highlights ongoing efforts by law enforcement and corrections officials to combat the flow of illegal drugs, cell phones and other prohibited items inside correctional facilities.
