A man has admitted killing Laura Mortimer and her 11 year old daughter Ella Dalby at their home in Gloucester.

Laura’s husband, Christopher Boon, was sentenced to life in prison with a minimum of 29 years for the ‘sustained and brutal’ attack, which happened in May. 

He stabbed Laura and Ella multiple times at their home in Dexter way and injured himself in the process. 

Laura’s friends say she told Boon to move out of the family home the day before and had been in good spirits. 

Police say he gave no account of what happened during an interview but in a phone call with officers shortly before he was arrested he admitted he had had an affair and in the lead up to the attack had argued with Laura, ending up in the kitchen, where he picked up the knife.

It is believed Ella was killed when she when she walked in on the scene.

During sentencing, Mrs Justice May spoke of the "unspeakable savagery" of Boon's actions.

The court also heard how Boon had been given a suspended sentence in 2010 for an attack on a former partner and in 2014, Laura also made an allegation of assault against him but later withdrew her statement.

Boon’s relationship with Laura has been described as “controlling” by her friends and officers are reminding those who are suffering abuse, who believe others are suffering abuse or know children affected by abuse, of where they can go for help.

Detective Chief Inspector Ruth Mather said: “Laura and Ella’s murders have devastated their loved ones and continue to have a profound effect on all who knew Laura and Ella and the wider community.

“My thoughts today are with Laura and Ella’s family and friends, who have shown unbelievable strength throughout and still have to confront the consequences of Boon’s actions on a daily basis.

“Boon should be clear though - they will never recover from what he did.

“Laura and Ella’s story shines a light on the nature of domestic abuse and the impact on children.

“Many people will be affected by the details and we're keen to make sure that the message about where to seek help gets out there.
