TABOR CITY, N.C. — A prison guard with the Tabor Correctional Institution was arrested last month in connection with a plan to rob and behead a business owner in Myrtle Beach.

The FBI received a tip in September that David Lawrence Wallace Jr. approached a fellow army reservist at a drill and wanted him to participate in robbing an armored car facility in Myrtle Beach sometime around Halloween or early 2015, WECT reports.

According to the criminal complaint, Wallace was a former employee of the facility, Garda Cash and Logistics, and he had knowledge of how the business operated.

Wallace told the reservist there would be $30 million in the armored car building and that it was lightly guarded on the weekends.

The criminal complaint said part of the plan included killing the owner or manager of the company by possibly beheading him and his wife to make it look like an act of terrorism.

The FBI has recorded conversations where Wallace talked about committing home invasions to acquire weapons for the heist.

Wallace is in the Darlington County Prison Facility awaiting trial.

Prison officials with the State of North Carolina confirm to WECT that Wallace has been on personal leave since his arrest on Nov. 17.
