It's been two years since Lindsay Ann Hawker was found murdered and buried in a bath of sand on a Tokyo apartment balcony. On the second anniversary of her death, Lindsay's sister Lisa and family are re-visiting Japan to raise the profile of the case in a renewed attempt to capture her killer.

Lisa, it's been two years since Lindsay was murdered in such a horrendous way, how have your family been?
It's been a really difficult two years. It's really difficult for any family that loses a family member. I think what's made it particularly difficult for us is that we lost Lindsay in such a horrific way and we've had to deal with it quite publicly as well which has been quite hard for us as a family.
But we're moving on, we're rebuilding our lives and I hope in some ways that people that have lost children can look at our family and my parents and think, 'Well, they're getting through this and so can I'. We're positive about the future but we won't give up looking for Lindsay's killer.
You've been battling for the whole two years to get justice for your sister. What keeps you going?

I think just remembering the kind of person that Lindsay was and what she would've done if it would've been me in that situation, and she would not have given up. We're not the sort of family to give up.
The past two years have been awful. As I say, dealing with it under the media spotlight has made it really difficult. But we're a strong family, we've remained close.
We've constantly spoken to each other about how we're feeling and I think that helps a lot. You just can't give up with these things, you have to keep going, there's no other option as far as I'm concerned.
It must be particularly difficult for you because the police have a very good idea of who did this and yet he hasn't been caught two years on.
My main problem with what's gone on was the fact that he [prime suspect Tatsuya Ichihashi] was ever allowed to get away in the first place.
I still can't understand that. But that's happened, we've dealt with that.
All we can do now is continue to support the police. They haven't captured him yet but we remain positive that they will do.
We know that they're trying everything they can. All we can do is support them and help them wherever we can just to keep it in the public profile.
What's your relationship been like with the Japanese officials?
We've always maintained a very good relationship with them. I think it's important to keep up a good relationship, keep up communication and help them wherever we can.
If it was a murder that had taken place in this country we've been told that resources would have been scaled down much sooner and it would have perhaps taken more of a back seat than it has done in Japan.
Because Japan's got such a low crime rate and because it was such a horrific crime it's remained in the public conscience and it's remained a serious case. So we're still positive that there's going to be a positive outcome.
You've asked Gordon Brown to intervene with the Japanese prime minister on your family's behalf. How involved have the British government been in this?
The British government have been more forthcoming but it's only been due to my parents' continued hard work.
Lisa Hawker makes another appeal for information in Japan
It's only because they haven't given up, they've fought from day one to try and get justice for Lindsay and it's only through them trying hard to open up new lines of communication that any of this has been possible.
I don't think it would have happened were it not for my mum and dad trying so hard to get to where we are now.
What are you hoping will be achieved from your visit on the second anniversary?
We're just hoping once again that somebody will see him, somebody will recognise the face and that a positive sighting will lead to his capture.
That's all we want. This has never been about us as a family trying to get any sort of attention for ourselves. We just want justice for Lindsay, for my sister.
