Lab Photographs of Tail Light Housing — Hartnett Examination
Hartnett's laboratory photographs of the removed taillight housing, including measurements. DNA swabs were taken from exterior surfaces, not protected interior areas.
About
Used by the prosecution to document Hartnett's swab methodology and the condition of the housing at examination. The defense relied on the same photographs to argue that the broad swab coverage across multiple exterior areas made it impossible to pinpoint the source location of any detected DNA.
Photographs of the passenger-side tail light housing taken at the laboratory during forensic chemist Maureen Hartnett's examination, including images with scale measurements. The photographs document the removed housing in lab conditions and establish that DNA swabs were taken only from exterior-facing surfaces, not interior protected areas.
