TEXARKANA, Texas (AP) — Four men who pleaded guilty to theft of government property in a Red River Army Depot billing scam are going to prison or must serve probation.

Kenneth Ray Shackelford was sentenced Friday to nearly three years in federal prison. The plea agreement reached in Texarkana also requires Shackelford to pay nearly $800,000 in restitution.

The Texarkana Gazette reports Shackelford was co-owner of now-closed Advantage Distributors in Texarkana.

The Red River Army Depot, about 10 miles east of Texarkana, employs a large civilian workforce. An indictment returned last September outlined a false invoice scheme involving tires, repairs and equipment.

Anthony Paul Vera was sentenced Friday to 32 months in prison and ordered to repay nearly $503,000.

William Robert Barr and William Randall Scott were put on probation and fined.
