The identity of Jack the Ripper, the notorious series of killers from the late 1800s in England, may eventually be known.

A DNA forensics published this month by two British researchers in the Journal of Forensic Science identifies Aaron Kosminski, a 23-year-old Polish barber and prime suspect at the time as a likely killer.

The "seed spots coincide with the sequences of one of the main suspects of the police, Aaron Kosminski," said the study authored by Jari Louhelainen of Liverpool John Moores University and David Miller of the University of Leeds.

The murderer, known as Jack the Ripper, killed at least five women in London's Whitechapel district from August to November 1888.

The authors of the study conducted genetic tests on blood and semen on a scarf found near the body of Catherine Eddowes, the fourth victim of the murderer whose severely mutilated body was discovered on September 30, 1888.

The brutal murders and mystery behind the identity and motive of the murderer have inspired countless novels, films and theories over the last 130 years.

Kosminski, who apparently disappeared after the killings, was previously named as a potential suspect, but his guilt was debates and was never confirmed.

The researchers said they have been analyzing the silk scarf for eight years and that, to their knowledge, "the cloth referred to in this work is the only known physical evidence with these murders. "

By analyzing fragments of the victim's and suspect's mitochondrial DNA, which is passed on by the mother alone, the researchers compared this to samples of living descendants Endants of Eddowes and Kosminski.

The article also states that the "observable" characteristics of the suspect derived from DNA are consistent with the only eyewitness accounts of the killings that law enforcement agencies found to be "significantly reliable."

The study said its findings represent the first "systematic molecular-level analysis of the only surviving physical evidence associated with the Jack the Ripper murders."
