Howard Barton Unruh (January 21, 1921 – October 19, 2009) was an American mass murderer (sometimes classified as a spree killer) who shot and killed 13 people (including three children) during a 12-minute walk through his neighborhood on September 6, 1949, in Camden, New Jersey, when he was 28 years old.
The incident became known as the "Walk of Death".
Unruh was found to be criminally insane, and died in 2009 after a lengthy illness at the age of 88, following 60 years of confinement.
