Colin Howell and Hazel Stewart appeared in court at Coleraine
A dentist and his ex-lover, who are accused of two murders almost 19 years ago, have been sent for trial.
Colin Howell and Hazel Stewart appeared before North Antrim Magistrates Court in Coleraine on Monday.
Mr Howell, 51, formerly of Glebe Road, Castlerock, and Mrs Stewart, 47, of Ballystrone Road, Coleraine are jointly charged with murdering their spouses.
The bodies of Leslie Howell and Trevor Buchanan were found in a fume-filled car in Castlerock on 19 May 1991.
A coroner originally ruled that Mrs Howell and RUC constable Trevor Buchanan had taken their own lives, but the case was reopened last year after new information was given to the police.
Mr Howell is also separately charged with drugging and indecently assaulting women patients at his clinic on separate dates over a 10-year period dating back to March 1998.
He was remanded in custody while Mrs Stewart was released on continuing bail, but she must report daily to police in Coleraine.
The trial is not expected to be heard until at least September.
