Another mass shooting where gunmen have entered a building shooting and killing. ~ sigh and my condolences to the loved ones of these victims ~ Has there been anything recently about gunwomen doing such a thing?

There was a couple (BF/GF) who executed two police officers in Las Vegas, not too long ago.  There was a school shooting in San Diego a long time ago by a girl.  There has only been one female serial killer ever identified.  Women only account for about 3% of the prison population and the vast majority are for property crimes, drugs, etc.
