Mr. Belin. How soon after 12:36 p.m., would you say the building was sealed off?
Mr. Harkness. It was sealed off then because I was back there and two other men.
Mr. Belin. You are talking about the back part of the building?
Mr. Harkness. Yes, sir.
Mr. Belin. What about the front part of the building? When was that sealed off?
Mr. Harkness. Inspector Sawyer and two officers were there.
Mr. Belin. By the time you got around to the front part of the building?
Mr. Harkness. Yes, sir; by the time I put the witness in his car, I went immediately to the back.
Mr. Belin. In other words, as I understand the sequence, you first went to the back of the building and had that sealed off first, or not?
Mr. Harkness. No, sir.
