So this is John Langan; he was pointed out as Vivian's accomplice when she when on her KC, Mo crime spree. They held up a series of small stores (shoe stores, drug stores, etc) for some small change. Langan was also involved with Clarence Sparger and a couple of robberies that put him on the FBI radar. I had requested the FBI to search to see if they still maintained the files on him. No such luck. Evidently "records responsive to my request were destroyed on 2/1/1990; 3/1/1993; and 3/1/1998. Oh well...all is lost.
The FBI may still have Vivian Chase's file...they have searched through records still in their possession and have found files that were microfilmed that may be relevant. Just one problem the FBI's microfilm readers are broken! A very nice Public Information Officer explained that they would not know if these were the files that I sought for at least another month by which time the microfilm machines would be fixed. I wish I had become interested in Vivian earlier in the 80's or 90's.
