▲ David Sinopoli, a murder suspect in Pennsylvania, arrested after 46 years


U.S. investigators, who did not give up on the murder case 46 years ago, finally caught the suspect using an abandoned coffee mug.



According to the New York Times (NYT) and the Lancaster County District Attorney's Office, Lancaster County, Pennsylvania, on the evening of December 5, 1975, 19-year-old Lindy Soubikler, a 19-year-old woman, stabbed her 19 times with a knife in an apartment in Manortownship, Pennsylvania. He was found stabbed to death.



Bickler, who worked as a clerk at a flower shop in the village, returned home from her husband's workplace, stopped by a bank and a supermarket that day, and was alone at her house.



Investigative authorities, including the police, formed a task force and interviewed more than 300 people in a horrific case in a small town.



Dozens of them were on the suspect list, but all were acquitted based on evidence such as blood type and DNA.



In 1997, 22 years after the incident, investigators sent Bickler's clothes worn at the time of her murder to a DNA laboratory to identify the suspect's semen, and then entered the suspect's semen into Cordis, a national DNA database run by the FBI. Uploaded.



However, there were no consistent results from Cordis, which had only 2 million data at the time.



It was DNA genealogy that provided the clue to the solution.



In December 2020, genetic genealogist Sissy Moore, who worked at the Parabon Nanolab in Virginia, analyzed the suspect's DNA and determined that the suspect's ancestry was from Gasperina, Italy, and that many family members had recently migrated from Italy.



Moore identified as a suspect David Sinopoli, 68, who lived in the same apartment building as the victim at the time, using various data after identifying people whose ancestors lived in Gasperina from among the 2,300 Italian residents who lived nearby at the time of the incident. .



Since then, the investigative authorities, which have been monitoring Sinopoli, were able to extract DNA from a coffee cup that Sinopoli drank and discarded in a trash can at Philadelphia International Airport in February, and confirmed that he was the culprit.



Authorities arrested Sinopoli on the 18th and reported it to Bickler's husband, and charged Sinopoli with murder.



Lancaster County District Attorney Heather Adams said at a news conference that it was "an endless pursuit of justice for Lindy Sue Bickler." "Law enforcement has never forgotten Bickler."
