Mr. Belin. How long, about?
Mr. Day. The past 7 years I have been—I have had immediate supervision of the crime-scene search section. It is our responsibility to go to the scene of the crime, take photographs, check for fingerprints, collect any other evidence that might be available, and primarily we are to assist the investigators with certain technical parts of the investigation.
Mr. Belin. Do you carry any equipment of any kind with you when you go there?
Mr. Day. Yes, sir. We have a station wagon equipped with fingerprint equipment, cameras, containers, various other articles that might be needed at the scene of the crime.
Mr. Belin. Have you had any special education or training or background insofar as your crime-scene work is concerned?
Mr. Day. In the matter of fingerprints, I have been assigned to the identification bureau 15 years. During that time I have attended schools, the Texas Department of Public Safety, on fingerprinting; also an advanced latent-print school conducted in Dallas by the Federal Bureau of Investigation. I have also had other schooling with the Texas Department of Public Safety and in the local department on crime-scene search and general investigative work.
Mr. Belin. Now, I believe you said that you were informed when you got there that they had located some hulls?
Mr. Day. Yes, sir.
Mr. Belin. What did you do then?
Mr. Day. I went to the northeast corner—southeast corner of the building, and first made photographs of the three hulls.
