Bonnie Parker 

Bonnie Parker and Clyde Barrow (1930-1934) were a Depression era 17-year old 
and 21-year old couple that started out in Dallas, Texas, eventually forming 
a gang that stole cars, robbed grocery stores, and banks in Texas, Oklahoma, 
Kansas, Missouri, Iowa, and Arkansas.  They shot and killed 16 victims, 13 
of which were police officers, and Bonnie is reported to have enjoyed putting 
a few extra bullets in the cops. Both were gunned down in a hail of bullets 
during a police ambush outside of Shreveport, Louisiana. A movie was made about 
them in 1967 called Bonnie & Clyde starring Warren Beatty and Faye Dunaway.
