Two charged with 1991 double murder

A man and woman were charged with the murder of a couple whose deaths 20 years ago were originally treated as suicide.

Policeman Trevor Buchanan, 31, and dentist’s wife Lesley Howell, 30, were found dead in a fume-filled car parked in the garage of a house in the seaside town of Castlerock, Co Derry in 1991. At the time police said they died in a suicide pact.
