Lester Harrison (serial killer)
Lester Harrison (born 1922) was an American serial killer who killed between four and six women in the area of Grant Park in Chicago, Illinois from 1970 to 1973. An ex-criminal who was found not guilty by reason of insanity for a 1951 prison murder, Harrison admitted responsibility for four of the latter killings, but was again ruled to be incapable of standing trial and instead interned at a mental health facility.
