Bank of Barry County Burglarized

I mentioned a couple of weeks ago that there were five bank heists in Barry County, Missouri, within the space of about two years from the late nineteen teens to the early nineteen twenties. Actually I've since discovered that there were six, but that's a subject for next week's post. For this week, I want to talk about the the robbery that I thought was the fifth of five but was actually the sixth of six. It happened in Cassville in early January 1922 and was not really a robbery but instead a burglary.
In the wee hours of the morning on January 5, an unknown number of burglars tunneled through a brick wall at the rear of the Bank of Barry County in Cassville, gaining access to the vault. The place where they tunneled through was the only spot in the vault weak enough that explosives were not needed to make a hole. The rest of the vault was steel reinforced, and the thieves could not have gotten through it except by use of explosives. This led investigators to speculate that at least one of the thieves knew the layout of the bank very well.
The burglars took twenty deposit boxes containing an undetermined amount of money, bonds, and other valuables, although one box alone was known to have contained over $700 in bonds. A number of other boxes containing a large amount of money were left alone.
The theft was discovered later the same morning, and a posse picked up the trail of the bandits north and northwest of Cassville in the direction of Pierce City, where several of the stolen deposit boxes were found empty and discarded along the road. As of late January, however, no arrests had been made in the case, and, as far as I've been able to determine, none were ever made.
