The daughter of a man who was found murdered in his home said she can't celebrate Christmas without him.
His killer has not been caught.
Mark's teenage daughter Hannah said the festive season has made it even harder to think there is someone out there "who has taken my dad away".
They will be enjoying Christmas while we as a family don’t get the opportunity to celebrate it. This has been a humungous shock for everybody because we have lost someone who is really special to us.
Hannah has added her voice to a police appeal urging anyone with information, "however minor", to come forward and help bring Mark's loved ones justice.
“If you feel it is hard to speak up, please know that it’s so much harder for us having to deal with losing him.
Detectives believe Mark's murderer may have stolen his designer watch after he died.
It's hoped it will help lead to his killer, and anyone who might have seen the watch, been offered it, or bought it, is being asked to contact Cheshire Police.
