Two inmates from the Spalding County Correctional Institute escaped a work detail in Thomaston on Wednesday, prompting a large manhunt, authorities confirmed.

James Rodney Owenby and Zachery Glenn Rampley, who are both part of the Ghost Face Gangsters, left their detail on Veterans Drive about noon, and several Thomaston police officers and Upson County deputies are searching for them, Upson County Sheriff Dan Kilgore told AJC.com.

Police said the duo stole a city work truck, and it’s unknown which direction they drove. The truck is a white single-cab 2010 Ford F-150, police said in a Facebook post.

The two were last seen wearing orange shirts and white pants with blue stripes, the City of Thomaston posted on Facebook. Owenby was described as 5-foot-6 and 160 pounds with brown eyes and brown hair, while Rampley is 5-foot-7 and 160 pounds with blue eyes and brown hair, according to Georgia Department of Corrections records.

Both have served one prior stint in prison, GDC records show. Owenby was convicted of first-degree burglary in Gordon County and spent about 15 months behind bars, while Rampley was convicted of obstruction and several driving-related crimes in Gordon County, netting him nearly five months in prison.

Owenby, who is serving a sentence for second-degree burglary and theft by taking in Murray County, isn’t set to be released until September 2022, GDC records show. Rampley was convicted on several crimes in Bartow County, including aggravated assault, obstruction and criminal trespass. He isn’t set to be released until April 2022.

According to the Anti-Defamation League, the Ghost Face Gangsters is one of the nearly 100 white supremacist prison gangs operating in the United States. The group originated in California in the 1970s, but a founding member started the Georgia group in 1998, according to the ADL.
