Sheriff Dillingham was shot and killed near Farley, Missouri, after pursuing a suspect who had gone on a shooting spree.

On August 19, 1900, the suspect attempted to kill his wife, Mary, but she escaped and went to Platte City for safety. At approximately 7:30 am on August 20th, the suspect, physician Dr. Sterling Price "Sturley" Harrington, was attempting to locate his wife when in the presence of Sterling's ten-year-old daughter, Maude, he shot and killed his uncle, James Wallace, and his mother-in-law, Mary Wallace with a revolver. Dr. Harrington, accompanied by Maude, then drove a buggy to Leavenworth, Kansas where he purchased a .41 caliber Winchester rifle from the W.W. Carney gun store. News of the shootings was sent to Platte City by telegraph from East Leavenworth, about 4 miles from the town of Farley. Sheriff John Dillingham rallied a posse, comprised of his son, Henry Dillingham, Liv Berry and Joseph Elgin and traveled the eight miles to Farley to arrest Harrington.

Dr. Harrington and Maude then went to the William Wiehe's General Store in Farley where he again left Maude in the carriage and entered the store. Harrington approached Wiehe and two other men, H.H. Moss and John Polk, and requested money. After being refused he approached the store clerk, Dan Cannon, and asked the clerk to loan him $4 from the till. When Cannon refused Harrington presented a pistol and robbed him at gunpoint. As Harrington left the store he lowered his revolver and Cannon produce a revolver from beneath the counter and opened fire. Cannon and Harrington exchanged gunfire with little effect but Cannon's last round struck Harrington's revolver, disabling the weapon and cutting off two of his fingers. Cannon dropped behind the counter and falsely announced he had been shot. Harrington threw the useless weapon away and drew another and stepped into the store's doorway.

Sheriff Dillingham confronted Harrington as he exited the General Store and they exchanged gunfire. Harrington shot through the store's doorway striking the sheriff in the forehead killing him instantly. The sheriff's bullet grazed Harrington's forehead. As Harrington stepped over the sheriff's body and out into the street, the sheriff's son, Deputy Henry Dillingham, shot Harrington three times in the chest, one bullet passing through the left breast, another in the left chest between his third and fourth rib and one round fatally pierced Harrington's heart.

Sterling Harrington was a heavy drinker, had previously submitted to treatment for alcoholism taking the Keeley "gold" cure in Kansas City, but returned to drinking and began abusing cocaine as well. Two years prior to the slayings Harrington attempted to kill G.S. Meyers, a fellow Mason, and was expelled from the order.

Deputy Henry Dillingham, 22, finished out his father's term as sheriff.

Sheriff Dillingham also served as Platte City Marshal until he successfully ran for Platte County Sheriff. Interred: Platte City Cemetery, Platte City, Missouri.
