At the High Court in Edinburgh Lady Stacey sentenced Yvonne Lambert to six years in prison after she was found guilty of the culpable homicide of David McLaughlin on the 14 July 2010 at Maxwell Drive, Inverness.

On sentencing Lady Stacey made the following statement in court:

“You have been convicted of taking another person's life by stabbing. 

No sentence I can pass nor any remorse you express can go any way towards assuaging the grief felt by Mr McLaughlin's family. That includes not only his brothers, but your mother and of course your own children, because by your action you took the life of the father of your 3 children. In all of the circumstances I have to mark the severity of the situation by imposing a custodial sentence.  It may be that excessive consumption of alcohol had some part to play in this incident, and I know that you know that is not an excuse.

I accept that you were in the house for hours before the incident. I do accept that you expressed remorse immediately after the incident, as I have heard all of the evidence in the case including tape and video recordings. I accept that remorse is genuine; and you do not need me to tell you that you will have to live for the rest of your life with the knowledge that your reckless and wicked action has taken a life and caused grief and disruption in other people's lives, most especially in the lives of your children.

I have listened to all that Mr Thomson ably said on your behalf. I have had the benefit of information including a social enquiry report and statements from Mr McLaughlin’s brothers, your mother, your family and your friend. I am grateful to all for taking the time to write to me.

The sentence which I impose is one of 6 years imprisonment”.
