This is "lady in the lake" murder victim Kamila Garsztka at Brighton rail station on what police think was her last journey.

She was captured on security cameras about to board a train.

Kamila spent that night with her boyfriend in her home town of Bedford and disappeared the next day.

Her body was found by canoeists in a lake at Bedford's Priory Marina on Tuesday this week.

Detectives hunting the killer last night told The Argus: "The solution to this mystery may be found in Brighton.

"The trip from Brighton railway station to Bedford could well have been her last." Kamila, 26, was from Poland and had been living in Bedford for 18 months.

She qualified as an accountant in Poland and was in England for employment and to improve her language.

She shared a house with her brother and other friends and spoke to her parents in Poland by telephone twice a week without fail. Kamila went on a day trip to Brighton on December 12 and was collected by her boyfriend from the train station at Bedford about midnight.

They went back to his flat where she stayed the night. The following morning her boyfriend left her at their flat and went to work. When he returned home about 11.45pm that night, she had gone, leaving behind her handbag, mobile phone and bank card.

It is believed her body had been in the lake for some time.

A post mortem carried out on Wednesday proved inconclusive as to cause of death and further toxicology and histology tests were being carried out.

A Bedfordshire Police spokeswoman said: "We are anxious to talk to anyone who may have seen Kamila or know her movements when she was in Brighton."

Detective Inspector Ged McCarthy, one of the senior investigators working on Kamila's case, said the team wanted to hear from anyone at all who knew her.

"This inquiry is far from concluded.

We have yet to establish how Kamila died, what her last movements were, or how she ended up in the marina.

"Her death is being treated as suspicious. It is absolutely essential, that anyone who knew Kamila, however slightly, comes forward to speak to us.

"You may think your information is unimportant, but it really could be a vital link in this case."
