People acquitted by reason of insanity

Anthony "Tony" George Kiritsis (August 13, 1932 – January 28, 2005) was an American kidnapper.
Kiritsis was a resident of Indianapolis, Indiana, and had fallen behind on mortgage payments for a piece of real estate. In early February 1977, when his mortgage broker Richard O. Hall refused to give him additional time to pay, Kiritsis became convinced that Hall and Hall's father wanted the property. The property's value had increased and could be sold at a high profit. Hall claimed that he had proof of this in writing.

Jeanne Weber (7 October 1874 – 5 July 1918) was a French serial killer. She strangled at least 10 children, including her own. She was both convicted of murder and declared insane in 1908; she hanged herself ten years later.
