In the wake of the release of a new theory on the identity of Jack the Ripper, the infamous Victorian murderer, the body of his final victim is likely to be exhumed.

The body of East End prostitute Mary Jane Kelly will likely be exhumed after the Ministry of Justice indicated that it will grant a licence for the Ripper's last victim.

The Real Mary Kelly, written by Dr Wynne Weston-Davies, chronicles the theory of Jack Ripper's identity in detail.

Dr Weston-Davies claims that the Ripper was a man known as Francis Spurzheim Craig, a journalist who reported on police courts in the East End of London in 1888.

According to Dr Weston-Davies, Craig killed his wife Kelly as an act of revenge after she secretly returned to prostitution shortly after her marriage in 1885.

He adds that the murders of four other women acted as a 'cover' for his act of vengeance – making the crime seem like the work of a serial killer, not a spurned husband.

Dr Weston-Davies also intends to prove through DNA testing that Kelly was his great aunt. By proving that the body in Kelly's grave is indeed of his great aunt, the connection between her and Francis Craig will be clearer and his theory will have greater weight.

Back in 1888, Jack the Ripper was believed to have killed at least five women, all of them prostitutes in the Whitechapel area of London. As of now, hundreds of theories exist as to his identity, though none of them have been proven.
