Mr. Hubert. You mean your normal station was not at headquarters?
Mr. Vaughn. Oh, no, sir.
Mr. Hubert. Where was your normal station?
Mr. Vaughn. At this particular month, being the month we worked days, and I work relief—I don't work any certain district—and I work just more or less wherever I am needed.
Mr. Hubert. So, they let you know at your home in some way?
Mr. Vaughn. No, sir; I had already reported for work. I was working with squad 105 that particular morning, which is in the downtown area.
Mr. Hubert. That's a patrol car?
Mr. Vaughn. Yes—district 105, and approximately at 9 a.m. I got a call to call 511, which is patrol headquarters. Officer L. C. Taylor, who answered the phone, advised me to report to the city hall and park my car and report to 511.
Mr. Hubert. What is 511?
Mr. Vaughn. Which would be the patrol office—that's the extension number which is commonly referred to as such.
