A CSI investigation, UW style: Help identify this week's Lost and Found Film

Editor's Note: The UW Audio Visual Services Materials Library has more than 1,200 reels of film from the late 1940s through the early 1970s, documenting life at the University through telecourses, commercial films and original productions. Some of the short films are easily identifiable, but many more remain mysteries. Who shot these films and why? Can you help answer those questions? Faculty and staff can use the comments field at the end of the story to send ideas. Those outside the University can e-mail filmarc@u.washington.edu.

This week's film, Arson, depicts CSI, UW style. It opens with three men walking down the street toward a fire-damaged building. We see a sign: "Danger, No Trespassing on These Premises, Karl Hermann, State Fire Marshall and Insurance Commissioner." The three men go in and begin inspecting the scene. They look at the doorway and a burnt handkerchief on the living room rug. Finally they take a sample of the rug and place it in a metal container.

The scene shifts to the UW, where a man goes through some double doors, one marked "Department of Health Services" and the other "Department of Environmental Health." He hands the sample to a man in a lab coat, who puts the sample through a series of experiments involving charts and graphs.

The film is silent. It was made in about 1971 and is just under two minutes. What UW Film Archives Specialist Hannah Palin would like to know is, the location of the fire and why the two UW departments were involved in investigating it, and what kind of research is being conducted on the arson samples. And as always, she wants to know why this film was taken and how it was used.

Thanks to UW Radiation Safety Officer Stan Addison, Palin learned there is a book describing the experiments depicted in last week's film, and she welcomes further comments. Now see if you can help her out with Arson.

The Arson film sounds familiar to me.  The Environmental Health Lab helped the state fire marshals to investigate samples taken from arson sites to determine if accelerant were used or was the fire accidently caused .  If i could view the film, I might be able to help identify the film and the personnel shown in it.

I recently received the following extremely helpful email from Lee Monteith, 
Senior Lecturer Emeritus and Former Laboratory Supervisor of the Env. Health Lab:

During the time period of the early 70s, the state did not have a crime lab
capable of chemically analyzing for arson. As a public service, the
Dept. of Env. Health worked with the State Fire Marshal. In a suspected
arson cases, the fire marshals would collect samples of material that might
have been soaked with flammable solvents from the fire scene. That is what
was shown in the first part of the film--the fire investigators collecting
samples of carpet in a building that had burned.

Then they would bring the samples to the Environmental Health Lab for analysis.  
The latter scenes show one of the lab chemists accepting the sample, enclosing it in a
desiccator that was attached to a sophisticated laboratory apparatus for
analysis. The vapors were drawn from the desiccator and frozen out by
liquid nitrogen into the inlet of the GC/MS and were identified. The
apparatus was one of the first gas chromatograph/mass spectrometers (GC/MS)
in the world that was applied to the analysis of occupational health,
environmental samples and arson samples.

The graphs that were shown, display the chromatographic peaks that
identified the type of gasoline or flammable solvent that the arsonist used
to start the fire. With the GC/MS data we could usually tell what brand of
gas or the origin of the solvents to help tie the arson to the specific
suspects.

This film clip could have been produced to help the marshal get funding for
further facilities and assistance, or it could have been made to provide
court room evidence for a particular case or cases.

The arson work was only a small part of the service and research work of the
Env. Health Lab and the solvent analysis with GC/MS only a minor
demonstration of its capabilities.
