The boy's teeth and bits of bone were discovered in the home's chimney. Holmes' murder spree finally ended when he was arrested in Boston on November 17, 1894, after being tracked there from Philadelphia by the Pinkertons. He was held on an outstanding warrant for horse theft in Texas, as the authorities had become more suspicious at this point and Holmes appeared poised to flee the country in the company of his unsuspecting third wife. Following the discovery of Alice and Nellie's bodies, in July 1895, Chicago police and reporters began investigating Holmes' building in Englewood, now locally referred to as "The Castle". Though many sensational claims were made, no evidence was found which could have convicted Holmes in Chicago. According to Selzer, stories of torture equipment found in the building are 20th-century fiction. In October 1895, Holmes was put on trial for the murder of Benjamin Pitezel, and was found guilty and sentenced to death. By then, it was evident Holmes had also murdered the Pitezel children. Following his conviction, Holmes confessed to 27 murders in Chicago, Indianapolis, and Toronto (though some persons he "confessed" to murdering were still alive), and six attempted murders. Holmes was paid $7,500 (worth $ today) by the Hearst newspapers in exchange for his confession, which was quickly found to be mostly nonsense. Holmes gave various contradictory accounts of his life, initially claiming innocence and later that he was possessed by Satan. His propensity for lying has made it difficult for researchers to ascertain the truth on the basis of his statements. While writing his confessions in prison, Holmes mentioned how drastically his facial appearance had changed since his imprisonment. He described his new, grim appearance as "gruesome and taking a Satanical Cast", and wrote he was now convinced that after everything that he had done, he was beginning to resemble the Devil. On May 7, 1896, Holmes was hanged at Moyamensing Prison, also known as the Philadelphia County Prison, for the murder of Pitezel. Until the moment of his death, Holmes remained calm and amiable, showing very few signs of fear, anxiety or depression. Despite this, he asked for his coffin to be contained in cement and buried 10 feet deep, because he was concerned grave robbers would steal his body and use it for dissection. Holmes' neck did not snap; he instead strangled to death slowly, twitching for over 15 minutes before being pronounced dead 20 minutes after the trap had been sprung. On New Year's Eve 1909, Hedgepeth, who had been pardoned for informing on Holmes, was shot and killed by police officer Edward Jaburek during a holdup at a Chicago saloon.
