POLICE are treating the death of a couple whose bodies were found at their flat in Bridge of Allan, Stirlingshire on Thursday afternoon as a case of murder-suicide.

Post mortems were carried out on Mr Robert Bruce and his wife, Jean, yesterday. Police said they were not looking for anyone else in connection with the case.

Detective Chief Superintendent John Ogg, Central Scotland Police's director of crime management, said: ''As a result of the post mortem we can say that we are not looking for anyone else.''

The post mortem is understood to have revealed that Mr Bruce suffocated his wife with a pillow or cushion.

He is then thought to have remained in the flat with her body for five days, drinking alone, before killing himself with a cocktail of pain killers and prescribed drugs.

Police found empty pill bottles scattered over the living room of the flat when they broke in. A toxicologist's report will reveal exactly what drugs were used. No note was found.

Detectives think that Mrs Bruce was murdered by her husband early on the evening of Wednesday May 13.

A team of detectives led by the head of Stirling CID, Detective Inspector Gordon McKenzie, investigated the case.

Police appealed for anyone who had been in the area of the flat in the last week to contact them in case they have information that might throw further light on the incident.

They also called for information from anyone who was in the area, of the beer garden of the nearby Westerton Arms and who might have heard or seen a scuffle.

Mr Bruce, 48, and Mrs Bruce, 47, lived alone in the flat. Villagers said they were suffering from debt problems, and feared losing their home.
