THE net is closing in on the killer of a mother after detectives investigating her murder have obtained DNA evidence 12 years on.

THE net is closing in on the killer of a mother after detectives investigating her murder have obtained DNA evidence 12 years on.

Nijole Siskeviciene, 44, from Wembley, was strangled and dumped behind a garage in Lancelot Road, Wembley, on October 20, 1998.

The killer has never been found but thanks to advances in scientific technology, detectives have identified a partial DNA profile from her body allowing any suspects to be eliminated from their inquiries.

Detective Superintendent, Keith Niven, who is heading the murder hunt, is calling for anyone who may know something to come forward.

He said: “Twelve years have now passed since the brutal murder of Nijole Siskeviciene but we have not given up hope of finding her killers.

“At the moment we do not know the identity of this person, all we need is a name to help us identify him or her. If you know please come forward to help us secure justice for Nijole and her family.”

DS Niven believes Ms Siskeviciene was murdered elsewhere and her body was dumped between 6.45pm and 7.30pm.

Days after the grim discovery, two anonymous letters were sent to Wembley Police Station, which backed DS Niven’s theory by claiming to have seen two men carrying a woman.

He believes the writers of both letters could hold the vital key to solving Ms Siskeviciene’s murder.

The letters are thought to have been written by two separate people and the first writer said they saw two black men carrying a woman out of a house in Lancelot Road, on the fateful day between 1.15pm and 2.30pm.

They added: ‘I am not much help, am I, I am too old, I am afraid to go outside my door.’

The second letter described seeing two dark men lifting a woman wearing blue jeans and a blue jumper, the writer said: ‘Sorry, I do not want my family in this sort of thing, in case they come after my family.’

When Ms Siskeviciene was found she was wearing jeans, a pale round-necked jumper, distinctive multi-coloured three quarter length cardigan and open toed shoes.

Her wristwatch, black leather handbag and its contents, including house keys, were all missing and have never been found.

Ms Siskeviciene had moved to the UK from Lithuania in 1997 and previously lived in Harlesden and Kilburn, before moving to the Wembley area six days before she died.

At the time of her death she had a teenage son who is still struggling to come to terms with his mother’s murder.

He said: “My mum was murdered such a long time ago and I really need to know why this happened to her so that I can begin to move on with my life.”

A �10,000 reward is on offer for information leading to the conviction of whoever is responsible for her death.
