£5,000 reward to find Jane

The talented musician has not been seen since she vanished from her home in Shaftesbury Road, almost four weeks ago.

Detectives leading the investigation into her disappearance fear she has been murdered but admit they still have no definite leads.

They hope the reward will jog memories and encourage someone to come forward.

The £5,000 will be paid to anyone with information leading to the discovery her whereabouts, dead or alive.

Jane's partner Malcolm Sentance, mother Liz Longhurst and sister Sue Barnett, were due to attend a Press conference in Brighton this afternoon to renew their appeals for help.

They are adamant Miss Longhurst, 31, would not have walked away from her life.

No money has been withdrawn from her accounts and she has made no attempt to contact friends or family.

Jane taught at Uplands School for children with learning disabilities in Hollingdean, Brighton.

Extensive searches with trained officers have taken place across Sussex and on the county borders.

Detective Inspector Chris Standard, deputy senior investigating officer for Operation Keen, said: "We hope that by putting up the reward today we will prompt someone's memory and subsequently locate Jane.

"The investigation team is becoming increasingly frustrated by the lack of information.

"Since Jane went missing four weeks ago tomorrow, officers have worked tirelessly and around the clock to try and find her.

"The investigation has certainly confirmed that Jane had no intention of leaving of her own choice. We think something serious has happened to Jane and that she has been killed.

"I urge people to cast their minds back to March 14, Red Nose Day and try to remember if they saw anything at all suspicious or out of the ordinary. If so then please contact police as soon as possible so we can try and end this nightmare for Jane's family."

Anyone with information should contact the Operation Keen incident room at Brighton police station on 0845 6070999.
