In 2009, Matthew von Konrat, a plant scientist at The Field Museum of Natural History acquired an intriguing telephone name from the Federal Bureau of Investigation (FBI). The officers suspected that 4 staff at Burr Oak Cemetery close to Illinois had illegally exhumed previous stays, dumped them elsewhere on the cemetery grounds, and offered the unique burial plots. During their investigation, they discovered an uncommon piece of proof with the reburied our bodies that they believed von Konrat might use to reply their questions.

“Investigators found a moss sample that was probably the size of your thumbnail,” stated von Konrat. The brokers needed to know what species of moss it was, “how did it get there, and how long it had been buried with the human remains.” As an enormous fan of detective reveals, von Konrat jumped on the alternative to use his experience to assist the investigation.
By carefully inspecting the moss samples, von Konrat and his group established a timeline of when the reburials befell, providing essential solutions to resolve the case.1 Since then, the researchers have additionally assisted regulation enforcement officers in different felony investigations, highlighting the applying and utility of botanical samples in forensic science.
Moss Sheds Light on Grave Robbing
When von Konrat agreed to assist the FBI on the Burr Oak Cemetery case, his first purpose was to find out the precise species of moss current. von Konrat and his group examined the samples below the microscope and in contrast them with preserved specimens from the herbarium on the Field Museum. This helped them establish the pattern because the frequent pocket moss, Fissidens taxifolius.
When von Konrat and his group inspected the crime scene the place the our bodies had been reburied, they didn’t discover crops of this species rising naturally. “We surveyed the cemetery, and the same species of moss was growing in an area [of] the cemetery where law enforcement suspected the bodies had been dug up from,” stated von Konrat, validating that the moss appeared on the crime scene when the grave robbers reburied the exhumed our bodies.

Next, the researchers studied the biochemical properties of the moss sampled from the crime scene. They in contrast the expansion and fluorescence emitted by chlorophyll molecules of the forensic pattern and a historic herbarium pattern. The outcomes indicated that the moss had been moved to the crime scene inside the final yr, giving a transparent timeframe inside which the previous stays had been reburied. “And that was critical because the accused, their whole line of defense was that this happened several years ago before their employment,” defined von Konrat.
This case from 2009 set the ball rolling for von Konrat to make use of plant proof to assist different felony investigations.
Moss in Other Criminal Investigations
In 2011, when Katherine “Baby Kate” Philips disappeared, the police suspected her father of murdering her. However, unable to both get a confession out of him or find Baby Kate’s physique, the investigation hit a snag.
The detectives turned to von Konrat and his group, who analyzed the moss caught on the underside of Baby Kate’s father’s sneakers.2 By collaborating with different botanists who discovered flowering crops clinging onto the accused’s shoe, the researchers discovered some solutions. “We went to the crime scene…and we were trying to find the same composition of plants because that narrowed down the search areas where the body might have been buried,” defined von Konrat.

Based on their plant analyses, there was just one space the place Baby Kate might have been buried, shrinking the search from seven counties to 50 sq. ft. Though the police by no means recovered Baby Kate’s physique, her father ultimately confessed that he had buried her stays in an space that the researchers had narrowed down, serving to the prosecution get a conviction.
Further highlighting moss as essential forensic proof, von Konrat and his group are engaged on an ongoing case by learning moss rising on a suitcase concerned in against the law.
Using Moss to Solve Crimes: The Big Picture
In hindsight, von Konrat believes that some of the attention-grabbing points of utilizing his plant science experience in forensic investigations has been the chance to work with regulation enforcement. “An exciting component was actually collaborating with a different team, different groups of people, the FBI, the sheriff’s office, the state attorneys,” he stated. “Because everyone has a different lens, and that was a unique experience.”
Going ahead, von Konrat hopes that such instances will assist spotlight the significance of mosses in felony investigations. Beyond forensics, “it’s an opportunity to highlight and raise the profile of this overlooked but fascinating and important group of plants,” stated von Konrat.
