KAREN Boyd says her son Clay hasn't been the same since he was brutally assaulted in an unprovoked attack during a night out in Yeppoon in December 2012.
Clay was allegedly punched three times in the back of the head in a hotel toilet. He was planning to leave the premises when he was set on again in a passageway.
It was here his alleged attacker landed a blow to his face that was so savage it severed a major artery.
Ms Boyd said that as well as inflicting severe physical injuries, the alleged assault had left Clay emotionally scarred.
"It has really traumatised him," she said yesterday. "He's only just started to talk about it now.
"It is shocking that one incident can change the course of your life. This has changed my son's life forever."
Ms Boyd remembers clearly the fateful night that 20-year-old Clay decided to join friends for a few drinks at a Yeppoon hotel on December 22.
She can't erase the image of her bloodied son standing in the gutter when she arrived at the hotel.
And she'll never forget the crippling pain and suffering her son endured in the days following the alleged attack.
Clay's nose was badly broken and he bled profusely for nearly two days.
"He was in such pain he couldn't talk, he couldn't breathe. There was a bowl catching the blood.
"He was thumping the bed with his fists. It was dreadful to watch. He was so distressed."
Clay lost two litres of blood before he got to the operating theatre.
Ms Boyd is forever grateful that her son got to see Christmas 2012.
But she is heartbroken that the alleged assault has changed her son so profoundly.
She said Clay was "a good boy" who always saw good in others.
"Now he sees things entirely differently and he trusts no one," Karen said. "We notice a huge difference in him.
"This alcohol-fuelled violence is just not acceptable. It should be zero tolerance and that needs to be backed up by the courts and the police."
A man, now aged 22, was charged with grievous bodily harm in relation to the incident. He has been committed to stand trial in the Rockhampton District Court on a date to be set.
