From Victoria Adams' WC interview:
"There was a man that was standing on the corner of Houston and Elm asking questions there. He was dressed in a suit and a hat, and when I encountered Avery Davis going down, we asked who he was, because he was questioning people as if he were a police officer, and we noticed him take a colored boy away on a motorcycle, and this man was asking questions very efficaciously, and we said, "I guess he is maybe a reporter," and later on on television, there was a man that looked very similar to him, and he was identified as Ruby.
And on questioning some police officer, they said they had witnesses to the fact that he was in the Dallas Morning News at the time. And I don't know whether that is relevant or what."
