Well, finished reading the copies I made at the archives. Always enlightening but this time just a little sad. One of the documents that I copied was a report on Vivian Chase's funeral. At the end of the report there's an addendum detailing what happened the night she was killed.
Vivian and other members of her gang had finished a robbery. They decided to have a few drinks. Vivian said something to one of the men, Clarence Sparger, and he shot her then he ran away from the group. Evidently the remaining gang members took Vivian to St. Luke's Hospital. They left her inside the car at the hospital's parking lot. She died a couple of hours before anyone found her body.
There has always been speculation that Vivian was executed because of a double cross. The truth is it was a drunken quarrel.
