How moss helped convict grave robbers of a Chicago cemetery

In a shocking revelation from a decade-old case, the use of moss has emerged as a pivotal piece of forensic evidence in the conviction of grave robbers at Burr Oak Cemetery, located in Alsip, a suburb of Chicago. The cemetery, which has served as a resting place for many prominent African Americans since its establishment in 1927, became the center of a scandal in 2009 when it was discovered that employees were exhuming graves to resell burial plots, discarding older remains in an undignified manner. The case, which led to convictions in 2015, has been further explored in a recent paper published in the journal Forensic Sciences Research. Co-author Matt von Konrat, who oversees the botany collections at the Field Museum in Chicago, emphasized the importance of mosses and other bryophyte plants in forensic investigations. He noted that while these plants have been utilized as evidence in only a handful of cases over the past century, they possess unique qualities that can provide valuable timelines and habitat information that enhance traditional forensic methods. Von Konrat's research aims to elevate the significance of these often-overlooked plants in forensic science, encouraging investigators to incorporate botanical evidence into their inquiries more frequently. He expressed a hope that the publication would inspire further exploration of natural history collections and their application in forensic contexts, revealing potential uses that have yet to be discovered. The troubling events at Burr Oak Cemetery were initially uncovered in June 2009 when Sgt. Jason Moran, who led the investigation, encountered skeletal remains protruding from dirt piles during his first visit. His inquiries into the actions of cemetery staff and families of the deceased confirmed that graves had been desecrated and original headstones removed to accommodate new burials. This alarming discovery prompted the involvement of the FBI to ensure justice was served.
