Lindy Sue Beichler Biography
Who was Lindy Sue Beichler ?
A 68-year-old Lancaster man has been charged with the murder of Lindy Sue Beichler nearly 47 years after she was found dead in her Millersville-area apartment, Lancaster County law enforcement officials announced Monday.
David Sinopoli, of the 300 block of Faulkner Drive, has been charged with felony homicide in Beichler’s slaying, Lancaster County District Attorney Heather Adams said at a news conference at the Lancaster County Courthouse on Monday. .
Sinopoli was arrested without incident at his home on Sunday, Adams said.
He has been living in Lancaster for decades after Beichler’s murder as investigators tried to charge a suspect in the case.
Beichler was found dead in her Manor Township apartment on the night of December 5, 1975. She had been stabbed 19 times in the throat, upper torso, and back after returning home from the grocery store that same night. Family members discovered her body around 8:46 p.m., Adams said.
Investigators found blood outside the front door and entryway, along with several other bloodstains on the carpet in the home. Her grocery bags were still on the table and there were signs of a struggle throughout the house, police said at the time.
Beichler was found on the floor, lying on her back with a knife in her neck. The knife had a kitchen towel wrapped around the handle, investigators said. It matched knives found in a knife block in Beichler’s kitchen.
Manor Township police, state police and many other law enforcement agencies have been investigating the case ever since, questioning and acquitting dozens of people over the ensuing decades.
“The arrest is the culmination of decades of investigation by multiple agencies and, most recently, the investigation by County Detective Chris Erb, Larry Martin and their extensive investigation with the assistance of Assistant District Attorney Christine Wilson,” Adams’ office said. in a press release.
The investigation was also aided by information provided by Parabon NanoLabs, the Virginia-based agency that helped crack the cold case of Christy Mirack’s murder in 2018.
In September 2019, Parabon NanoLabs provided a composite sketch of the suspect in Beichler’s case based on a DNA profile she compiled from evidence collected at the scene in 1975, Adams said.
The composites revealed the suspect’s characteristics, including skin tone, eye color and hair color, according to Adams. The sketches showed the suspect at 25 and 65 years old.
In December 2020, Adams’ office asked Parabon NanoLabs to continue genetic genealogy analysis.
Parabon’s genetic genealogy research produced Sinopoli as a possible person of interest in the case, based on her Italian ancestry.
Investigators needed to collect a sample of Sinopoli’s DNA to determine if it matched evidence taken at the scene in 1975. So, on February 11, they surreptitiously collected a coffee cup that Sinopoli used and discarded while at Philadelphia International Airport. according to Adams.
The coffee cup was sent to DNA Labs International for analysis, Adams said. In April, test results determined that the DNA sample left in the coffee cup was a mix provided by a single male collaborator. The DNA was then sent to Cybergenetics, a Pittsburgh-based lab that specializes in separating DNA mixtures.
Cybergenetics’ analysis determined that the DNA from the coffee cup matched that from semen collected from Beichler’s underwear at the murder scene in 1975. The match statistic was around 10 billion, Adams said.
Detectives then consulted with a blood spatter expert to see if the blood left on Beichler’s clothing would be consistent with being left behind by a suspect, Adams said. The expert identified two blood stains left on the exposed portion of Beichler’s pantyhose, and investigators sent the stains to DNA Labs for analysis.
Tests found that the blood drops matched the DNA profile left on Beichler’s underwear.
“This arrest would not have been possible without the help of CeCe Moore and Parabon NanoLabs,” Adams said. “We are incredibly grateful for the work they do and their commitment to ensuring justice for victims and their loved ones.
