I have a test where I am given the following article, what is an answer for the question: Who is the henchman pursuing the bank robber and his wife? ?

Serving four years of his ten-year sentence for armed robbery, Carter "Doc" McCoy is denied parole from a Texas prison. When his wife Carol visits him, he tells her to do whatever is necessary to make a deal with Jack Beynon, a corrupt businessman in San Antonio, to free him. Beynon uses his influence and obtains Doc's parole on the condition that he take part in a bank robbery with two of his henchmen, Rudy and Frank. Frank kills a guard, then Rudy attempts a double-cross, killing Frank and drawing on Doc, who quickly reacts and shoots Rudy several times. Doc takes the $500,000 ($3.0 million today) and leaves. Rudy, having secretly worn a bulletproof vest, is only wounded.
Doc meets with Beynon, who attempts a double-cross before Carol shoots and kills him. Doc realizes that Carol had sex with Beynon to secure his parole.  Doc angrily gathers up the money and, after a bitter quarrel, the couple flees for the border at El Paso.
A bloodied Rudy forces rural veterinarian Harold and his wife Fran to treat his injuries, then kidnaps them to pursue Doc and Carol. Beynon's brother Cully and his thugs also pursue the McCoys. At a train station, a con man swaps locker keys with Carol and steals their bag of money. Doc follows him onto a train and forcefully takes it back. The injured con man and a train passenger – a boy whom Doc had rebuked for squirting him with a water gun – are taken to the police station, where they identify Doc's mug shot.
