Bishopbriggs shooting: 'No other suspects' in husband and wife deaths

• Police outside the Bishopbriggs home of Jim and Diane Harley, who were found dead last night

The couple, who are understood to have two teenage children, were found at their home in Bishopbriggs by police officers yesterday evening.

It is understood detectives are investigating the theory that one of the couple shot the other before taking their own life.

Taxi driver Mr Harley, 51, was a director of a firm with connections to the Edinburgh-based security business Rock Steady.

Neighbour Bill Kerr, 56, said: "They were very much a family. Both of their children are still at school. They have been here for 15 years or more.

"They were very nice. I found out when I came home last night that something had happened. It is a very big shock as it's a close-knit community here."

Another neighbour, aged 73, described Mr and Mrs Harley as a "lovely couple".

He said: "I am really shocked. I have never known any hassle around here. It is very quiet.

"Last night I counted seven police officers plus three forensic people. An ambulance came around 3am this morning.

"I didn't see him around that much but he was a taxi driver. He didn't talk much in the street but they were a very nice couple."

One neighbour, who did not want to be named, said: "It is a shock to have something like this happen in the street. It's very quiet normally.

"They seemed quite a happy family, with a teenage girl and boy. I never heard of anything going on at all, they seemed quite normal."

Outside the house, two police officers stood next to a blue Volkswagen Passat parked in the driveway. The curtains and blinds of the house were closed. Two other officers could be seen at the side of the house.

A spokeswoman for Strathclyde Police said: "At around 7.45pm on Tuesday March 16 the bodies of a male and female were found within a property on St Andrews Avenue, Bishopbriggs.

"A full report will be sent to the procurator fiscal and post-mortems will be carried out in due course to establish the exact cause of death."
