Crimestoppers has offered a £10,000 reward for information on the killing of Nahid Almanea which leads to the arrest and conviction of the killer.
Nahid Almanea, 31, was found off Avon Way in Colchester on June 17 after having been stabbed several times.
It is believed the Saudi Arabian student left her home on Woodrow Way before being attacked as she made her way onto the Salary Brook Trail at around 10.40am.
Ann Scott, Eastern Regional Manager for Crimestoppers, said: "The murder of Nahid has left Colchester residents feeling shocked, saddened and distressed. However, during this time of immense tragedy the whole community can unite in helping Essex Police find the person or persons responsible for this horrific murder.
"I would urge anyone with information no matter how insignificant they feel it might be or anyone with niggling suspicions they are unsure of to contact us anonymously safe in the knowledge that their identity will not be revealed.
"You have nothing to fear by giving us information as we never ask for your name or take any personal details. We don't record our calls and can't trace calls/computers. Those giving information won't have to go onto to give a statement to police or go to court. You don't even have to speak to someone if you don't want to – you can give information online.
"It really is quick, safe and easy. And, it could be vital in helping police to bring this person or persons to justice. In over 25 years we have never revealed anyone's identity."
The charity are also increasing their previous award of £5,000 for information on the murder of James Attfield to £10,000, although police do not yet know whether the attacks have been carried out by the same person.
If you have any information on either incident please contact Crimestoppers anonymously on 0800 555 111 or through the anonymous online form at www.crimestoppers-uk.org. NOTE Rewards will only be payable for information passed to Crimestoppers on 0800 555 111. Information passed to Crimestoppers via their online secure form at www.crimestoppers-uk.orgor given directly to Police will not qualify.
If the two murders are positively linked by Police then the claimant will only be eligible to claim up to £10,000.
