The family of a teacher found murdered in Japan are launching an e-mail campaign to try to find a man suspected of killing her.
Lindsay Ann Hawker went to Japan to teach in October 2006
Lindsay Ann Hawker, 22, from Brandon near Coventry, was found dead in a bath filled with sand on a balcony in Ichikawa, east of Tokyo, in March.
Her body was found when police visited Tatsuya Ichihashi's flat, but he fled before he could be arrested.
Police have been searching for the 28-year-old since.
Mr Ichihashi had reportedly asked the former Leeds University student for English lessons a week before her death.
He fled his apartment when police arrived to investigate him, losing his shoes and a rucksack in a chase.
The Hawker family said they had received an e-mail from Japanese police saying that at the time they went to Mr Ichihashi's flat there was no evidence suggesting they should arrest him as it was a missing person's inquiry.

Bill Hawker said: "We think it is disgraceful that the Japanese police let Ichihashi go when our daughter's body was lying just yards away."
Miss Hawker's parents are sending out an e-mail around the world which will carry a picture of their daughter and Mr Ichihashi.
The e-mail is titled "Don't forget Lindsay Hawker" and asks the reader for help to catch her killer and to forward it on to as many people as possible.
It outlines the manner of Miss Hawker's death and says a "gaping hole" has been left in the lives of her family and boyfriend.
"Lindsay's family are heartbroken by her brutal death and above all they want justice for Lindsay, who didn't deserve to die in this way," the e-mails reads.
On Friday, a Japanese police officer said that although they have some information, they still do not have clear clues to his whereabouts.
