THE mother of a North-East teenager murdered by a man she met on Facebook has invited its creator, Mark Zuckerberg, to visit the place where she died.

Andrea Hall issued the challenge to the US billionaire after he called for children under the age of 13 to be allowed on the social networking site.

She said she felt “physically sick” after Mr Zuckerberg revealed his intention to overturn a US law which would allow under-13s to legally sign up to Facebook.

Mrs Hall believes encouraging children onto Facebook will expose them to sex beasts like Peter Chapman, 32, who groomed her daughter, Ashleigh, 17, a Darlington College childcare student, online with a fake name, before raping and killing her. Her body was found on farmland near Sedgefield, County Durham, in October 2009.

Mrs Hall said she wants to show Mr Zuckerberg the place where Ashleigh’s body was dumped, to bring home the dangers to him.

“It feels like everything happened after Ashleigh died and it’s all been forgotten about,” she said.

“You try and get your point across, but it feels like Facebook aren’t listening. They’re not interested.

“I want the people who make these decisions to come and meet Ashleigh’s little sisters and listen to their memories of her.

“They still ask why that man had to take her away. I’m never going to let them use Facebook.”

Mrs Hall has banned her three remaining daughters, Olivia, eight, Ellie, six, and Evie, two, from using the internet at home.

In Britain, under-13s are banned from Facebook under a voluntary good practice code, partly introduced after Ashleigh’s murder.

Home Secretary Theresa May had pledged to look into the proposals after Ashleigh’s death but, despite a campaign by MPs, a Government consultation document launched last week on ways to manage sex offenders made no reference to the web crackdown.

Mrs Hall added: “There’s not a day goes by when I don’t think about her. She was my daughter and my best friend.

“There was nothing wrong with what she was doing.

“She was just a normal teenage girl who thought she’d met a nice boy online.”

Chapman was jailed for a minimum of 35 years for her murder.

Facebook declined to comment.
