On 3 May 1927 in Valladolid, Spain while on tour with Colo Colo, David Arellano encountered peritonitis after being hit by an opposing player during a match.
Harvey is also notable for having used numerous methods to kill, such as arsenic; cyanide; insulin; suffocation; miscellaneous poisons; morphine; turning off ventilators; administration of fluid tainted with hepatitis B and/or HIV (which resulted in a hepatitis infection, but no HIV infection, and illness rather than death); insertion of a coat hanger into a catheter, causing an abdominal puncture and subsequent peritonitis.
He died on 15 September 1932 of peritonitis at Pau, France, at the age of 35, and was succeeded by his son, William Robert Bradley Craven, 6th Earl of Craven.
