On June 30, 1943, Henry Ruhl, a transient farm worker who had absconded from parole in Washington, robbed and murdered Matt Katmo, a defense production worker, on a military reservation near Laramie, Wyoming. Katmo and a date were picnicking in the Telephone Canyon area when Ruhl demanded Katmo’s car and killed him when he resisted.
Ruhl was tried in the United States District Court for the District of Wyoming. He was convicted of first degree murder on May 26, 1944, and sentenced to death on June 30, 1944.
After his conviction was upheld on appeal, Henry Ruhl was executed in the gas chamber of the Wyoming State Penitentiary on April 27, 1945.
