Mr. HUTSON. Thirty minutes. Mr. BELIN. Why did you leave? Mr. HUTSON. I was relieved by my sergeant. Mr. BELIN. Did you let people go in that said they were employees within the building? Mr. HUTSON. No, sir. One lady came up that was an employee. I refused to let anyone enter except police officers. Mr. BELIN. Did you see anyone leave the building? Mr. HUTSON. No, sir. Mr. BELIN. Was your back to the building? Mr. HUTSON. Yes, sir. Mr. BELIN. Now there were lots of people milling around at that time, I assume? Mr. HUTSON. Not at the entrance, there wasn't when I first got there. There wasn't a big crowd around that building, but all the sirens coming in, that is what brought the big crowd. Mr. BELIN. Could you hear any witnesses say they had seen a rifle or anything from the building? Mr. HUTSON. No; I didn't. Mr. BELIN. Well, you left. What did you do when you were relieved from duty? Mr. HUTSON. As I was being released, I heard the radio dispatcher come on the radio and give a Signal 19, and that a shooting involving a police officer in the 500 block of East Jefferson, and he came back on shortly and said to check both 500 East Jefferson and East Tenth, that they weren't sure on the exact location. Mr. BELIN. Was this at about the time you were being released? Mr. HUTSON. Yes, sir. Mr. BELIN. Now when you first got the signal to go to Elm and Houston, did he say Elm and Houston? Mr. HUTSON. Elm and Houston, that is the location I heard. Mr. BELIN. How long do you feel that it took you to get from where you were on Main at that time? Mr. HUTSON. I was in the 1800 block of Main Street, eastbound, and I made a turn and used my siren and red lights, and the maximum amount of time it could have taken me would be 3 minutes. Mr. BELIN. So you got there in 3 minutes, and within 3 minutes after you heard the signal you were stopping people from going in? Mr. HUTSON. Yes. Mr. BELIN. You are nodding your head, yes? Mr. HUTSON. Yes. Mr. BELIN. Do you know how many minutes after the shooting you heard the first notice over the police radio? Mr. HUTSON. No, I don't. Mr. BELIN. At times you were working away from your police radio while you were picking up the signs, is that correct? Mr. HUTSON. Yes; and you can't hear the radio from a distance. Mr. BELIN. When you heard this news about this shooting in Oak Cliff--by the way, where was your regular station ordinarily? Mr. HUTSON. I worked west of Vernon on Jefferson. Mr. BELIN. Is that Oak Cliff? Mr. HUTSON. Yes; that is West Jefferson Boulevard. Mr. BELIN. What did you do after you heard about the shooting? Mr. HUTSON. I got on my motorcycle and I proceeded down through the triple underpass and up onto R. L. Thornton Freeway to Oak Cliff. Mr. BELIN. Where did you go? Mr. HUTSON. I exited off Jefferson and went to the 400 block of East Jefferson Boulevard and began a search of the two-story house behind 10th Street where the officer had been shot.
