Three former police officers and another man have lost their federal appeal over their convictions for a 2007 North Little Rock armored car robbery.
The 8th U.S. Circuit Court of Appeals on Tuesday upheld the convictions of Allen Clark, Jason Gilbert, Antonio Person and Sterling Platt.
Gilbert appealed his 3 1/2-year prison sentence, which the court also upheld.
Person, who is Gilbert's cousin, was sentenced to 12 years in prison for leading the robbery, in which more than $400,000 was stolen.
The defendants claimed on appeal that the government didn't have sufficient evidence to prove a conspiracy. The appeals court disagreed.
Gilbert was a Little Rock police officer, Clark was a Veterans Affairs officer and Platt was an officer at University of Arkansas for Medical Sciences.
