The grief-stricken family of tragic student Jane Khalaf are still waiting for answers.

They have expressed their anguish at a lack of answers about her death two months ago.

Jane’s parents, Rojin and Khalil, of Shelley, claimed they still feel in the dark about the action German authorities are taking to find out what caused her to collapse and die after a night out to celebrate the Cologne carnival. Jane, a politics student at Northumbria University, was on a placement to the German city.

Their plea for more information comes after the time limit set by Ulrich Bremer, the head prosecutor of the Prosecution Office of Cologne, who said it would some time take to get results of blood tests which he needs in order to continue an investigation.

Family and friends of Jane, who was anti-drugs, insist her drink must have been spiked after initial tests revealed levels of amphetamine and ecstasy in her system.

Mum Rojin, who lives in the family’s home in Parkwood Close in Shelley, also said they had not received any news from the Swedish Embassy, who had consular responsibility for Jane, who was born there after her parents fled Syria.

Rojin said: “We have tried to ring the relevant people for information but have not heard any news at all.

The German authorities are killing us by ignoring us.

“Some progress should have been made but even if it has not we think it’s only right that we are kept updated about the investigation as it concerns our daughter.

“It is incredibly frustrating as we are already going through such a lot at the moment that we do not need these delays on top.”

A Facebook page called Justice For Jane has been set up by three of Jane’s friends, Lottie Smith, chessy Hollingdale and Charlotte Lewis to demand that the investigation be stepped up.

They and volunteers are preparing to distribute 15,000 leaflets across the UK and Germany, which they hope will encourage more people to contact officials and sign a petition to urge for more enquiries to be taken.

Signatures on the petition have reached over 54,000, a figure that boomed over the Christmas period.

Lottie said: “We are continuing to get a great response from the public and hope that it forces our politicians to ask the German authorities to do more.

“We have also been in contact with a few celebrities about sharing the petition.”

The group also plan to go out in Huddersfield town centre on future Saturday nights to give out drink caps to prevent drinks being spiked and highlight what happened to Jane.

Mr Bremer said that he was still awaiting the results.

He said: “Investigations in the local case are not yet completed. We are still awaiting the findings of the Institute of Forensic Medicine.

“Until then, I can not announce anything new.”
