For parents everywhere, a child's 30th birthday is a milestone event. For mum Maxine Thompson Curl, the anniversary is a painful reminder of a grievous loss.
Her son Kristian Thompson died after an unprovoked one punch attack in the K2 nightclub in Consett in September 2010. Kristian from Burnopfield suffered a severe brain injury after hitting his head and spent seven days in a coma.
While he initially seemed to recover, his condition deteriorated before passing away in July 2011 at the age of 19. Maxine, who now lives in South Shields, has since campaigned tirelessly to raise awareness of the impact of one punch deaths, and now runs the One Punch UK charity.
