The daughter and son-in-law of an elderly couple who went missing from Mansfield in 1998, and whose bodies were found buried in their back garden, have been charged with murder.
Susan Patricia Edwards, 55, and Christopher John Edwards, 57, have each been charged with two counts of murder in relation to the deaths of William and Patricia Wycherley.
Nottinghamshire Police said remains found buried in the garden of a house in Blenheim Close in Forest Town, Mansfield, are believed to be those of the couple.
Post mortem results revealed they both died as a result of being shot.
Mr and Mrs Wycherley's daughter Susan and her husband Christopher were arrested at St Pancras International railway station in London on Wednesday evening on suspicion of the murders.
The pair, of no fixed address, will remain in police custody until their appearance before Nottingham magistrates tomorrow.
Officers made the grim discovery at the house in Mansfield on October 9 following a tip- off to police.
A murder inquiry was immediately launched after the bodies were unearthed.
A Nottinghamshire Police spokesman said formal identification has yet to be confirmed, but officers believe the remains are that of Mr and Mrs Wycherley, who lived at the house in the 1990s and, according to neighbours, disappeared in 1998.
Officers have said Mrs Wycherley is believed to have been born in Fulham, west London, and would now have been 79. Her husband would have been 100.
