Frank Geyer was an American police detective from Philadelphia, Pennsylvania, best known for his investigation of H. H. Holmes, one of America's first serial killers. Geyer was a longtime city employee of the Philadelphia Police Department, and in 1894 was assigned to investigate the Holmes-Pitezel Case. He published the story in his book The Holmes-Pitezel Case: a history of the greatest crime of the century and of the search for the missing Pitezel children. Son of Reuben K. Geyer and Camilla Buck, Frank Geyer died at the age of 65 due to La Grippe and his funeral was attended by hundreds of policemen and detectives.
The Holmes–Pitezel Case
's recorded crimes began in Chicago in 1893 when he opened a hotel called The World's Fair Hotel for the World's Columbian Exposition. The structure, built by Holmes, would later be known as the 'Murder Castle' because of the labyrinthine constructions on the top two floors, which he used to torture and kill many of his victims. In a 1937 article, the Chicago Tribune described: "There were rooms that had no doors. There were doors that had no rooms. A mysterious house it was indeed -- a crooked house, a reflex of the builder's own distorted mind. In that house occurred dark and eerie deeds." Boston police inspectors and a Pinkerton detective apprehended Holmes in 1894 in Boston on a coroner's warrant for insurance fraud perpetrated in Philadelphia; however, Boston officials did not find the warrant sufficient to hold Holmes so they contacted Fort Worth, Texas for an outstanding warrant of horse theft. Holmes volunteered to be extradited to Philadelphia for the insurance fraud as he felt he would receive a much lighter sentence. Texas was notorious for rendering harsh sentences to horse thieves. The City of PhiladelphiaPolice Department sent Detective Thomas Crawford to Boston to bring H. H. Holmes and his accomplice, Mrs. Carrie Pitezel, to Philadelphia for a trial. Philadelphia city detective Frank Geyer was tasked with investigating and the trail led him through the Mid West and Toronto, Canada, where he found the remains of two of the Pitezel children. They were the children of Benjamin Pitezel, Holmes's former partner in crime, whom he had murdered to commit life insurance fraud. Pitezel, however, was only involved in fraud and had no knowledge of the murders. The initial investigation was concerned with the insurance fraud but it soon became apparent that Holmes had killed Pitezel. In June 1895 Frank Geyer left Philadelphia to retrace Holmes's steps. His findings in Toronto led to further investigations of Holmes's Chicago property, which sealed his fate. Geyer used information from the unsent letters written by the Pitezel children which, for an unknown reason, were kept by Holmes. In Toronto, he found the bodies of Alice and Nellie Pitezel. He continued his search and found the burnt remains of Howard Pitezel, the third child, in a house Holmes had rented in Irvington, Indianapolis. Holmes was found guilty of four counts of murder in the first degree and six counts of attempted murder and executed in May 1896 at the age of 34. His total number of victims has been estimated at around 200. However Erik Larson, who wrote extensively about Holmes in The Devil in the White City, thought this was a gross exaggeration. Holmes himself confessed to 27 murders, unquestionably he killed nine times. That same year Frank Geyer published his book detailing the case. In the book George S. Graham, District Attorney of Philadelphia, described the story as "one of the most marvellous stories of modern times".
Several popular books falsely claimed Detective Geyer's wife and twelve-year-old daughter died in a fire shortly after he was assigned to investigate H. H. Holmes and the three missing Pitezel children. However, Geyer's beloved wife and daughter never died in a fire and continued to live well past his death in 1918.
