Day 1: Not only did housebreakers use skeleton keys in the past, but police detectives did also, especially when searching properties for evidence such as explosives, firearms and forgery equipment. #xmascountdown #crimedetection

Day 23: This is not Victorian but the first murder bag for detectives to use at murder scenes was created in 1924 by Home Office pathologist Sir Bernard Spilsbury, after he was shocked by the lack of hygiene at the examination of the scene of the murder of Emily Kaye. #xmascountdown #crimedetection

Happy December! I’m going to count down to Christmas with a rather unusual Advent calendar! Each day I’ll be showcasing an object used in crime detection. Follow my posts to find out what detectives used to help them solve crime in the Victorian and Edwardian periods #xmascountdown #crimedetection

Day 16: Police dogs were introduced into regional police forces in the early 1900s to aid in crime detection, as well as to protect their officers. Airedale terriers were the preferred breed, as they were as efficient as bloodhounds in tracking suspects but cheaper #xmascountdown #crimedetection

Day 22: The first blood test to differentiate human from animal blood was in 1901. Before that, analysis was often based on smell or appearance, or chemical reactions. I found some bloodstained pieces of fabric in a box at the archives, from a homicide case in 1890. #xmascountdown #crimedetection

Day 14: French criminologist Alphonse Bertillon created an anthropometric system of measuring habitual offenders, which was based on the length or width of 11 different body parts. in the UK, these measurements were taken and added to criminal records in the 1880s. #xmascountdown #crimedetection

Day 19: Like their uniformed colleagues, Victorian detectives used bulls eye lanterns for nocturnal investigations. Hooked onto their belt, they would use them to examine dark buildings and shady corners. They would also remove their boots so they could move silently. #xmascountdown #crimedetection

Day 15: Models of crime scenes were commissioned and used by detectives as evidence in court from the 1840s. They were a routine feature of trials by the 1870s. As well as a model of the building, they often included miniature versions of the furniture at the scene #xmascountdown #crimedetection

Day 12: The main form of communication between Victorian detectives during an investigation was a route form, which was a handwritten note passed between forces. Although the telegraph was available, they were still using route forms at the end of the 19th century. #xmascountdown #crimedetection

Day 8: The Fingerprint Bureau at Scotland Yard was created by Sir Edward Henry in 1901. The practice was gradually introduced into regional detective departments. In Birmingham the technique was first used successfully to investigate a burglary in 1905. This is my kit! #xmascountdown #crimedetection

Day 3: The telegraph was invented in 1837, and the first murderer was caught by this means in 1845. By the 1860s, most regional police detectives had access to telegraph machines which they used to keep in touch with the detective office and to contact other forces #xmascountdown #crimedetection

Day 7: French criminologist Alphonse Bertillon (see below) created the 'mugshot' which included a dual profile of offenders, and added them to criminal records at the Paris Sûreté. This became standard practice, and was adopted by British detectives in the late 1880s #xmascountdown #crimedetection
December 7, 2024 at 9:56 AM
Day 17: Alphonse Bertillon created a series of charts with detailed facial features to aid in the identification of habitual criminals. He used these with his measurements and mugshots to form a record card or 'portrait parlé' (spoken portrait) for individual offenders #xmascountdown #crimedetection

Day 11: One of the earliest CSI tools was the recording of footprints at a crime scene. This was mostly done by making a cast out of plaster of Paris, although some detective used wax. Although they experimented with other substances, they kept the traditional methods #xmascountdown #crimedetection

Day 2: The most important piece of detective kit in the Victorian era was his (there were no women!) customised notebook, which had blank pages for recording information. This one is from the Manchester City Police – sadly it's empty! #xmascountdown #crimedetection

Day 10: Cameras were introduced into police detective departments from the 1850s, and were mainly used to photograph offenders for criminal records. Pioneered by French criminologist Alphonse Bertillon, cameras were also used for recording a crime scene from the 1880s. #xmascountdown #crimedetection
December 10, 2024 at 9:09 AM
Day 20: In the late-19th century detectives created exhibits for trials, especially in homicide cases. This is the evidence for the prosecution of infamous baby farmer Amelia Dyer in 1896. It was discovered in the loft of Detective James Anderson's descendant in 2017. #xmascountdown #crimedetection
December 20, 2024 at 9:54 AM
Day 18: A standard feature of the Victorian detectives' kit was their handcuffs, which they called 'snaps'. 'Darby Cuffs' were the most commonly used handcuffs in the 19th century – they're quite heavy and would have been tricky to manage. They were locked with a key. #xmascountdown #crimedetection
December 18, 2024 at 9:51 AM
Day 4: Like Sherlock Holmes, Victorian detectives often donned disguises when on undercover missions, pretending to be workmen, sales reps and vicars. They even used false wigs and moustaches. When travelling for a case, they kept their outfits in a bag ready for use #xmascountdown #crimedetection
December 4, 2024 at 9:26 AM
Day 21: Victorian detectives used the Police Gazette to share descriptions of suspects and stolen items. Established in 1772, it was in circulation for almost 250 years until 2017. I've come across references to its use many times in historical police investigations. #xmascountdown #crimedetection

Day 9: The first test for arsenic was developed in 1833 by British chemist James Marsh, for use in a poisoning case. When George Bodle was fatally poisoned with coffee, his grandson John was tried, and the test was devised as evidence. Despite this, he was acquitted.

Day 5: Beat wheels were not only used for measuring the beat of uniformed officers but they were also used by police detectives in investigations to measure the distance and route of alleged perpetrators to a crime scene. This one is from the Bow Street Police Museum.

Day 13: In their role as prosecutors, Victorian detectives commissioned crime scene sketches as visual aids for court. They also used them for investigative purposes, such as plotting the route and movements of an alleged offender, or mapping the blood spatter. #xmascountdown #crimedetection
December 13, 2024 at 9:51 AM
Day 6: The centralised Habitual Criminal Register was introduced in 1869, but regional detectives created their own unique criminal records. Birmingham detective department had a tattoo register and Liverpool recorded the aliases and family names of known offenders.
