The Metropolitan Police yesterday launched a final appeal for witnesses in the unsolved murder of estate agent Suzy Lamplugh as her family mark 40 years since her disappearance.

Yesterday marked four decades since the young estate agent disappeared while showing a client around a house in Fulham.

No trace of her has ever been found, but she was legally declared dead in 1994, and the investigation became a murder inquiry.

The Suzy Lamplugh Trust was subsequently founded by her parents Diana and Paul and has pioneered personal safety as a life skill and a public policy priority. The trust also runs the National Stalking Helpline.

“It will always be difficult to bring somebody to justice for Suzy’s murder.”

Their work continues and the Metropolitan Police this week said its officers plan to follow up a further 30 potential witness leads during the next 12 months.

But if no useful information is discovered, the case will be classified as inactive, meaning officers will continue to respond to new leads if they emerge but will no longer be regularly working on the case.

Difficult case

DCI Teresa Foster said in a Met Police video: “This case continues to resonate with the public simply because she has never been found.

“When a case is moving into inactive, that doesn’t mean we are closing it down.

“If new information comes in we will review and assess it.

“It will always be difficult to bring somebody to justice for Suzy’s murder as people have passed away and memories fade.

“For us, the focus as investigators and for her family is finding Suzy and bringing her home.”

Never forget

It comes as the Suzy Lamplugh Trust launched a social media campaign to encourage people to sign its petition calling for MPs to put stalking, harassment and personal safety back on the Government agenda.

Supports can also donate to there trust and join its free  bystander training to ensure every victim and survivor can access the specialist support they need.

The trust said: “Forty years should have been enough. Enough to stop stalking. Enough to stop harassment. Enough to stop abuse.

“Yet every day, thousands of people continue to live in fear. Victims of stalking alter their daily routines, leave jobs, move homes, and lose relationships in an attempt to escape persistent and unwanted behaviour.

“Our #40YearsShouldHaveBeenEnough is about more than remembering Suzy. It is about ensuring that her legacy continues to drive change. Forty years on, we remember Suzy, stand with those affected by stalking, harassment and abuse today, and renew our commitment to creating a safer society.

“Together, we can help ensure that one day, forty years really will have been enough.”
