The man accused of killing RCMP Const. Shaelyn Yang in a Burnaby park has been found mentally unfit to stand trial.
Jongwon Ham, who appeared by video conference in B.C. Supreme Court in Vancouver, is charged with first-degree murder in the stabbing death of Yang in October 2022.

B.C. Supreme Court Justice Michael Tammen says Ham’s psychosis is getting worse and “his delusions prevent him from making rational decisions” about the court process.
As the trial was due to begin, Tammen instead ordered the fitness hearing to determine if Ham had the mental capacity to understand the charge and if he could take part in his own defence.
Two psychiatrists told the hearing that Ham suffers from a psychotic disorder and the court heard both doctors shared the opinion he is unfit for trial.
Yang, a mental health and outreach worker for the RCMP, was stabbed to death on Oct. 18, 2022, when she tried to speak to a man in a tent in Broadview Park in Burnaby, B.C.
