Professor Patricia Wiltshire (born 1942 in Monmouthshire, South Wales) is a forensic ecologist, botanist and palynologist. [1] She has been consulted by police forces and industry in almost 300 investigations in several countries [2] and has been instrumental in solving several high-profile crimes, including the killings of Sarah Payne and Millie Dowler, the cold case of Christopher Laverack, the Soham murders, and the Ipswich serial murders. [3]
Wiltshire was born in 1942 in the coal-mining valleys of Monmouthshire, South Wales. [4] [5] When she suffered severe burns in a home accident at the age of seven, followed by repeated chest infections that permanently damaged her lungs, her education was put on hold. She spent her convalescence reading encyclopaedias. [5] After working as a medical laboratory technician, she moved on to a career in the business world and then studied botany at King's College London. She lectured there for several years in microbial and general ecology before taking up a post at the Institute of Archaeology at University College London. [6] [4] She was later responsible for setting up a Masters' course in forensic archaeological science which ran successfully and continued after she left UCL.
As a forensic scientist in the Soham murder inquiry, Wiltshire's analysis of soil and plant evidence from clothing, footwear, and a vehicle, yielded trace evidence that linked Ian Huntley to the place where the victims (Jessica Chapman and Holly Wells) were found. Observation and experimentation of plant growth at the deposition site enabled her to estimate the time that the girls had been placed in the ditch very accurately. Her evidence was important in the conviction of Ian Huntley.
In the 2007 Christopher Laverack murder case, three decades after the nine-year-old's murder, Wiltshire linked the unusual pollen and other plant matter on the victim's clothing, along with the ornamental brick used to keep him submerged after death, with that found on the property of his uncle, Melvyn Read, thus providing substantial evidence to implicate Read. The investigation, spanning three decades, was Humberside Police's longest-running unsolved murder case, and was solved in 2012. [7]
Wiltshire is an Independent Councillor on Mole Valley District Council, along with her husband, David Hawksworth. [8]
Forensic science, also known as criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law.
Forensic palynology is a subdiscipline of palynology, that aims to prove or disprove a relationship among objects, people, and places that may pertain to both criminal and civil cases. Pollen can reveal where a person or object has been, because regions of the world, countries, and even different parts of a single garden will have a distinctive pollen assemblage. Pollen evidence can also reveal the season in which a particular object picked up the pollen.
Patricia Cornwell is an American crime writer. She is known for her best-selling novels featuring medical examiner Kay Scarpetta, of which the first was inspired by a series of sensational murders in Richmond, Virginia, where most of the stories are set. The plots are notable for their emphasis on forensic science, which has influenced later TV treatments of police work. Cornwell has also initiated new research into the Jack the Ripper killings, incriminating the popular British artist Walter Sickert. Her books have sold more than 100 million copies.
Henry Chang-Yu Lee is a Chinese-American forensic scientist. He founded the Henry C. Lee Institute of Forensic Science, affiliated with the University of New Haven. He has worked on numerous prominent cases. In July 2023, a federal court found that Lee had fabricated evidence that sent two teens to prison for 30 years.
Trace evidence is created when objects make contact, and material is transferred. This type of evidence is usually not visible to the eye and requires specific tools and techniques to be obtained. Due to this, trace evidence is often overlooked, and investigators must be trained to detect it. This type of evidence can link a victim to suspects and a victim or suspect to the crime scene.
The CSI effect describes the various ways in which the exaggerated portrayal of forensic science on crime television shows such as CSI: Crime Scene Investigation influences public perception. The term was first reported in a 2004 USA Today article describing the effect being made on trial jurors by television programs featuring forensic science.
Helle Crafts was a Danish flight attendant who was murdered by her husband, Eastern Air Lines pilot Richard Crafts. Her death led to the state of Connecticut's first murder conviction without the victim's body.
Forensic biology involves the application of biological principles and techniques within the context of law enforcement investigations.

He was known to police as a prolific home burglar.
A pollen calendar is used to show the peak pollen times for different types of plant pollen, which causes allergic reactions in certain people.
The Soham murders were a double child murder committed in Soham, Cambridgeshire, England on 4 August 2002. The victims were two 10-year-old girls, Holly Marie Wells and Jessica Amiee Chapman, who were lured into the home of a local resident and school caretaker, Ian Kevin Huntley, who subsequently murdered the children—likely via asphyxiation—before disposing of their bodies in an irrigation ditch close to RAF Lakenheath in Suffolk. The girls' bodies were discovered on 17 August 2002.
