YesEnetic material on a coffee mug led investigators in the US state of Pennsylvania to an alleged criminal more than 45 years after the murder of student Lindy Sue Beakler. Lancaster County Attorney said David Sinopoli, 68, was arrested over the weekend in East Hempfield Township, west of Philadelphia. Sinopoli allegedly sexually abused Beachler in December 1975 before stabbing him 19 times.
In the decades that followed, judicial officers followed several signs of potential criminals. 25 years ago, investigators had managed to secure a DNA trace of a man on Beakler’s underwear. However, a comparison with profiles from the CODIS database, which collects genetic information from criminals, yielded no results.
Three years ago, the public prosecutor launched a laboratory to examine the genetic material discovered in underwear. With the help of the laboratory, investigators identified the culprit. The analyzes also indicated that the killer had Italian roots. Suspicion soon fell on Sinopoli, who lived in the same house in the mid-1970s as Bechler. When the 68-year-old threw a coffee mug at a Philadelphia airport in February, investigators picked up the mug. Investigations have now revealed that the genetic material on the coffee mug matched that of DNA investigators found on her underwear after the murder of Lindy Sue Bichler.
