From: F.D. Silas
To recommend that Division 6 obtain the blood types of Leo Ryan, Anne [Ann] Moore and James Warren Jones and forward same to the Laboratory Division, care of SA [name withheld].
During the Laboratory examination of the .357 Magnum Ruger revolver recovered in Jonestown, Guyana, SA [name withheld] removed a quantity of dried material which preliminary analysis has proven to be blood. Since this weapon has been alleged to have been associated with Jones and could have been used in the shooting of Ryan, Anne Moore and Jones, the Laboratory should compare the blood types of these individuals with the blood from the barrel.
That Division 6 obtain the blood types of these individuals.
