Her shoulder was dislocated and her purse and cell phone were missing. The coroner declared Federica had died due to natural causes—but did she? Enter Paola Magni, a pathologist who studies creatures “that arrive opportunistically at crime scenes like uninvited party guests, from flies to barnacles,” creatures that help her bring criminals to justice and solace to living loved ones.

Her own research and collaborative spirit continue to push the boundaries of forensic entomology. In a paper published in June 2023 in the scientific journal Insects, she and her co-authors outlined protocols for best practices in bug-based crime-solving—for example, routinely obtaining temperature readings from meteorological stations near crime scenes, to accurately factor weather considerations into analyses, and inspecting soil surrounding a corpse for insects rather than strictly on the body itself. In another study, also published in Insects, in July, she and her colleagues wrapped cotton and other common fabrics around 99 stillborn piglets, to simulate human remains, and examined how blowflies, carrion beetles and other unsavory beings ate through the clothing over several weeks. The results showed that bugs can modify existing cuts and tears in fabric or even introduce new cuts and tears that investigators could easily assume are caused by bullets or knives; the paper illustrated how easily police and medical examiners might be led astray by assumptions about analyses that don’t incorporate cutting-edge research about bugs. And in September, she was a co-author of another study, published in the journal Forensic Sciences and produced in cooperation with police in India, that showed how studying ant activity and resultant bloodstain patterns can provide clues about the circumstances surrounding a person’s death, including whether the body has been moved.
