The man behind one of the pornographic web sites highlighted in the Jane Longhurst murder case has been exposed.

Frans van der Hulst, from The Netherlands, has been identified as the owner of one of the web sites Graham Coutts regularly visited before acting out his macabre fantasy of strangling the special-needs teacher.

Coutts, 35, was found guilty of murdering Jane at his flat in Waterloo Street, Hove, last March.

Lewes Crown court had heard how he strangled her with a pair of tights before hiding her body at a storage unit on the Lewes Road, Brighton. He visited her body ten times before removing it and taking it to Wiggonholt Common, near Pulborough, where he set it alight.

When Coutts was arrested it was discovered he had spent hours trawling through the internet for violent images before and after Jane's murder.

Van der Hulst, 50, told the Mail on Sunday: "I've read all the criticism but I'm doing nothing illegal. I don't feel responsible for what happened to Jane Longhurst. The only person responsible is Graham Coutts."

Jane's family has won MPs' backing in the fight to close down hardcore porn internet sites.

They are asking ministers to review the Obscene Publications Act so hardcore porn sites promoting violence against women will be closed down or filtered.

The campaign is being spearheaded by Jane's mother, Liz Longhurst, 72, who said: "This man doesn't think he's doing anything wrong. He's not doing anything illegal and that is why the law has to be updated.

"I don't think these people will admit it's immoral and that's the trouble. There's an awful lot of people who are doing this, making huge amounts of money. It's nauseating."

She asked people to write to their MPs and support the call for violent sex sites to be shut down.

Brighton Pavilion MP David Lepper and a Labour colleagues have tabled an Early Day Motion calling for a change in the law.
