Mr. RANKIN. At that time? Mr. CURRY. At that time. Now this would only have been, it couldn't have possibly been over 2 or 3 minutes prior to the shooting, so apparently he went right down that ramp and he got in behind some of these newspaper reporters or news media and detectives, and as Oswald was brought out he sprang from behind one of my detectives and took about two steps and shoved a gun in Oswald's side and pulled the trigger. This officer, in talking to him, he made a report, he swears that he didn't see anybody go in there. Mr. RANKIN. By this officer, you mean Vaughn? Mr. CURRY. Officer Vaughn. He did, I asked him myself or asked the investigating officers to see if he wouldn't take a polygraph test concerning this, just to verify his position in it, and he agreed to take the polygraph test and did take the polygraph test and the polygraph test revealed that he was not aware that Ruby came in while he stepped, when he stepped away from the entrance of that door. Now I am not here to place the blame on anybody because, as I have said previously, as head of the department, I have got to accept the responsibility for what goes on there. But if Officer Vaughn had properly carried out his assignment, I don't believe that Ruby could have gotten into the basement of the city hall. Mr. McCLOY. Unless he had credentials, media credentials? Mr. CURRY. That is correct. Mr. McCLOY. We haven't verified whether or not he did have anything? Mr. CURRY. We haven't been able to verify that. There were none found on his person. Mr. RANKIN. Did you make any inquiry as to whether or not any of the police force were involved with Ruby in this shooting? Mr. CURRY. We got reports and interrogated every officer who was there. Mr. RANKIN. What did you find out? Mr. CURRY. We didn't find any officer who knew he was down there or that had in any way assisted him in getting there. No one. Mr. RANKIN. You are satisfied that none of them were involved in trying to have Oswald shot? Mr. CURRY. Yes, sir; I certainly am. Mr. RANKIN. Did you make inquiry to determine whether there was any evidence that anyone else was involved with Ruby in trying to shoot Oswald? Mr. CURRY. We made every effort we could in our investigation. We were not able to determine any tieup between any other individual and Ruby or Oswald. Mr. RANKIN. Did you make any inquiry to determine whether or not anyone else was involved with Oswald in the assassination of the President? Mr. CURRY. We attempted to. Every lead we came upon we followed it out to see whether or not we could make any connection between Ruby, Oswald, or any other group. Mr. RANKIN. Did you discover any evidence that would tend to show that Oswald had any support in the assassination? Mr. CURRY. No; we did not. Mr. RANKIN. Did you discover any evidence that would prove Ruby was involved with any other person in the killing of Oswald? Mr. CURRY. We were not able to determine any connection.
