Robert Elmer Kleasen (September 20, 1934 – April 21, 2003) was an American who was convicted and sentenced to death in 1975 for the murder of two Mormon missionaries near Austin, Texas.
The murders have popularly, albeit inaccurately, been cited as an inspiration for the horror film The Texas Chain Saw Massacre.
Kleasen's conviction was later overturned and Kleasen immigrated to the United Kingdom, where he remarried and was eventually imprisoned on gun violations.
Kleasen died in the UK while fighting extradition back to the US for retrial on the murder charges.
