In a BC Supreme Court notice of civil claim, Amrit Singh Bunwait claims Sukhdeep Singh Sandhu shot him in the neck during a union induction celebration at the Riverside Banquet Hall on Jan. 16, 2013.
Bunwait is also suing Sandhu's family for allegedly failing to properly supervise the 28-year-old "when they knew or ought to have known that he was exhibiting symptoms of a mental disorder including hallucinations and paranoia."
Not criminally responsible
According to the claim, the banquet hall event erupted into gunfire when Sandhu arrived with a weapon and shot an attendee in the face. He allegedly then attempted to shoot the same victim again at close range, but his gun jammed.
"While the defendant (Sandhu) attempted to unjam the firearm, another attendee or attendees of the Banquet Hall forced him to the ground and subdued him momentarily, during which time (Sandhu) discharged his weapon several more times aimlessly, thereby shooting (Bunwait)," the claim says.
Sandhu was initially charged with three counts of attempted murder, one count of aggravated assault and one count of dangerous driving. He was found not criminally responsible due to mental disorder this summer.
Bunwait claims Sandhu exhibited signs of mental illness as early as 2004 and had at least once physically attacked his brother. He says Sandhu's family were concerned about his behaviour, but claims Sandhu refused to seek help.
At the same time, Bunwait claims Sandhu's family permitted him to have an illegal firearm when they knew he was struggling with mental illness.
Bunwait is also suing the union and Riverside Banquet Hall. He claims the hall was the site of a deadly shooting in 2001 and two other violent incidents in the years that followed.
He claims to have suffered injuries which have caused him pain, suffering and loss of enjoyment of life.
None of the claims have been proven in court.
