DNA from coffee cup credited in arrest in 1975 cold-case murder

Lancaster, Pa. — Authorities have announced an arrest in the stabbing death of a 19-year-old woman in Pennsylvania almost a half-century ago, crediting advances in DNA technology and genetic genealogical research.

Lancaster County prosecutors and Manor Township police say a criminal homicide charge has been filed against 68-year-old David Sinopoli in the December 1975 murder of Lindy Sue Beichler.

"Lindy Sue Beichler was 19 when her life was brutally taken away from her 46 years ago in the sanctity of her own home," District Attorney Heather Adams said. She said she hoped the arrest "brings some sense of relief to the victim's loved ones and to the community (who) for the last 46 years have had no answers."
