Jack The Ripper's identity has been a huge unsolved mystery since 1888.
With forensic investigation still unheard of during the Victorian era, the notorious serial killer was able to get away with killing five prostitutes in Whitechapel, London before completely disappearing from the face of the earth after ten weeks
However, for New South Wales English teacher Richard Patterson, the mystery has already been solved.
Backed by his research of 20 years, Patterson is vouching Jack The Ripper real identity to be British poet Francis Thompson.
Thompson, who wrote "The Hound Of Heaven" and other works, reportedly had surgical experience thus giving him the expertise to cut up those women with professional precision.
"Thompson kept a dissecting knife under his coat, and he was taught a rare surgical procedure that was found in the mutilations of more than one of the Ripper victims," he said, according to Express UK, adding that he gained experience by helping with surgery and is "known to have cut up heaps and heaps of cadavers while a student."
The educator further cites that Thompson moved to London in 1885 from Lancashire to become writer.
After living a hard life in the city, he was offered a place to stay by a prostitute, who presumably became more than his landlady.
However, their relationship eventually turned sour, a year into their romance, when the poet declared that he was going to publish his works.
"The moment he told her he was finally published, she said she was leaving him because the public would not understand their relationship," Patterson continued.
Aside from being addicted to opium, the poet was also said to be mentally unstable.
Ending his only relationship most likely triggered his urge to hurt other women in the area.
"Soon before and soon after the murders, he wrote about killing female prostitutes with knives," the researcher continued.
According to Mirror, the Patterson started research on Jack The Ripper's identity when he came across Thompson's works in 1997. Almost two decades later, he can finally publish a book - titled "Francis Thompson - A Ripper Suspect.
He also insisted that there are more evidences of Thompson's involvement in the Whitechapel murders than any of the previous suspects over the years.
