MURDERERS who killed an entire family in one of the UK's most shocking crimes have been tied to an unsolved murder.

William Horncy, of Adeline Road in Bournemouth, and Kenneth Regan, of Wilton near Salisbury in Wiltshire, are currently serving whole life sentences for the notorious killing of the Chohan family in 2003.

Armajit Chohan was murdered by Regan and Horncy as part of a plan to steal Mr Chohan's freight business and use it as a front for drug running.

The two also murdered Armarjit’s 25-year-old wife Nancy and their two young sons, 18-month-old Devinder and two-month-old Ravinder, along with Nancy’s 51-year-old mother Charanjit Kaur.

The body of Mr Chohan, of Heston, West London, was found floating in the sea near Bournemouth Pier in April 2003 and his wife’s was recovered in the same area in July.

Mrs Kaur’s body was found in November 2003 in a bay off the Isle of Wight.

The bodies of the two boys have yet to be found.

Now Horncy and Regan have been named as suspects directly involved in the killing of 53-year-old Michael Schallamach, of Sunningdale Gardens, Bitterne in Southampton.

Mr Schallamach went missing in April 1992.

Officers investigating the case believe he was murdered by Regan and Horncy ten years before the deaths of the Chohan family.

At the time of Mr Schallamach’s disappearance, the police and his family were told by his associates that he had run away with another woman to live in Europe or Nigeria. His wife Yvonne even received a handwritten letter sent from France from a person, allegedly called Helen, stating they had run off together.

Detective Chief Superintendant Ben Snuggs of Hampshire Constabulary, said: “Did you write the letter? Do you know who did? Do you recognise this person’s handwriting? If so I would ask you to come forward and tell my officers what you know.

“You may know what happened to Michael Schallamach. It has been 24 year since he went missing. Friendships and allegiances change over the years. This may be the last opportunity to tell what you know to the police.

“Mr Schallamach’s family have spent almost a quarter of a century not knowing what happened to him and I’m appealing for the public to help us finally solve this long running murder enquiry.”

The appeal will be featured on the daytime BBC 1 TV programme, Crimewatch Roadshow today, Thursday, June 30.
