So, all those times on some old TV show, when a prisoner uses the old pretend-to-be-sick gag to escape the guards, that’s not so ridiculous. It actually does happen:
Police believe that Affante faked a seizure, chest pains, and difficulty breathing at the jail. The jail sent him to Parkland in an ambulance. He was unhancuffed for treatment, police said.
While being taken in a wheel chair for an X-ray early Wednesday, Affante jumped up and ran, police said. A Dallas police officer was not able to catch him.
