Amelia Arnold was beaten to death with a dumbbell bar by her boyfriend, Jack Wall, in front of their young daughter at the home they shared in Hadrian’s Walk, Stevenage, in November 2012.

Wall was found guilty of murdering the 19-year-old and burying her body in a shallow grave in Hatfield and is currently serving 19 years for the crime.

Amelia’s sister, Olivia Perrin, did a sponsored 10-mile walk last Friday to raise money for domestic violence charity Refuge, in a bid to help others in abusive relationships.

The 19-year-old, who says she plans to do more fundraising events in Amelia’s memory, said: “I want to help to protect other people in a similar situation to my sister.”
