Twenty-year-old Adam Chadwick was murdered while trying to stop three masked men entering his sister's house at Harehills in Leeds.
The carpet fitter - and devoted Leeds United fan - was shot on her doorstep 10 years ago - and just the day after celebrating his little daughter's third birthday.
Despite an extensive police investigation it's still not clear what the gang were doing there and police believe it was a case of mistaken identity. For his family, the heartache of their son's senseless murder continues.
Adam's father, Martin Chadwick hopes someone will be brave enough to come forward with information.
