The mystery of how a person killed their spouse in the toilet has remained unsolved for decades.
But now scientists have cracked the case of a young woman who may have been killed by a male who she had just met.
In a new study published in the journal Science, scientists at Harvard Medical School say they’ve found the DNA of the perpetrator and are trying to figure out who is responsible.
“The person who committed this act is a person who’s at high risk for suicide, and we don’t have a good way of identifying who that person might be,” said Dr. Andrew Rosenberg, a professor of forensic sciences at Harvard and a co-author of the paper.
“So we’re trying to find out who that may be.”
In the study, the researchers found that the DNA found on the man’s body matches the DNA on the victim’s DNA, and that the perpetrator is from New York City.
“This is an amazing discovery because we knew that there were a lot of women in New York who would have had a history of violence,” said lead author and graduate student Jonathan Clements, who is now working on an unrelated research project.
“In this case, there was no history of previous violence.”
The crime happened on March 14, 1990.
The victim, 22-year-old Tasha Jackson, was found dead in the woman’s bathroom by her boyfriend, Daniel Cerny.
He had been arrested the day before for a string of crimes, including assault and robbery.
Cerny has not been charged with the crime.
A coronavirus case was never found.
In the months that followed, Cernys body was discovered in a landfill.
The remains were found wrapped in a plastic bag.
Cernies remains were also found in a trash can near a dumpster.
When the police searched the landfill and found the body, they found that Cernymys DNA was on the body of a woman who had recently been pregnant.
They also found the same DNA on a sample taken from a man, identified as Dwayne Sutter, who had been stabbed several times.
Chen told ABC News that Creny had previously had a relationship with Jackson, and Cernyn was worried about the baby.
“I told him that he should take her to a safe place,” she said.
The next day, Crenys DNA appeared on the test of a DNA sample taken in 2015.
It matched Jackson’s DNA.
The next day it matched the DNA taken from the man, and the results were matched the day after that.
Chern and Crenyr found that Jackson’s husband, Anthony, also had been sexually assaulted and had been killed.
Anthony was found on March 21, 1990, a day before Jackson.
But because Anthony had recently gone to the hospital for treatment, Chern and her colleagues did not suspect Anthony was the killer.
After Jackson’s body was found, investigators were called to the landfill, and a team was brought in to examine the garbage.
The garbage was filled with blood and tissue, but there were no fingerprints on the tissue.
But a fingerprint on the garbage could be extracted.
A DNA test on the DNA extracted from the tissue revealed that the person who killed Jackson was a man named Dwayne Cernyd.
DNA analysis later showed that Chern was the person Cerndy was most likely dating.
“We know this because the two people were matched by their DNA,” said Rosenberg.
Cenys DNA match with Cernyr’s was a match to Cernytah Jackson’s.
Creny’s DNA was also a match with Jackson’s daughter, Courtney, who was 14 at the time.
“They are very close in age,” said Crenytah’s mother, Donna Jackson.
Carny and Jackson had been dating for two years, but Jackson left Cerncy shortly after she was married to Crenyd.
Clement said the DNA test may have provided evidence that Chen and Clynys relationship was going sour.
But he said it could not definitively prove Cernypys involvement in the crime and was not conclusive proof that Cenys killing was his.
“I don’t think we can prove it was Dwayne.
It may be someone else.
But I can’t say for certain.
I think that Dwayne’s DNA may be what gave the people in the community some confidence in the story that Dvin had killed his wife,” said Clement.
The research has led Crenty to pursue a new research project on the case.
He and his colleagues will use DNA testing to try to figure the age of the person killed.
They will also be trying to determine the person’s sexual orientation.
Clements said he is trying to get DNA testing performed on Jackson’s remains, but that it may not be possible.
“It would be like having the toothbrush and the toothpaste,” he said.
“The same toothbrush would not give the same results.”
