The man accused of killing the brother of Lapu Lapu Day festival massacre suspect Kai-Ji Adam Lo has pleaded guilty.Dwight Kematch, 39, was charged with second-degree murder after 31-year-old Alexander Lo was found dead in an East Vancouver home on January 29, 2024.Lo's cause of death has not been revealed. Kematch initially pleaded not guilty and had been ordered to stand trial. A pre-trial conference was scheduled for June 3, with a four-week trial set to kick off on October 6. In light of the guilty plea, entered July 25, there will be no trial. He will be sentenced on August 11.According to the Detroit Free Press, just days before murdering Lo, Kematch allegedly sent threats to the mayor of Hamtramck, Michigan and members of the city council."He specified the time and place, during city council meetings, so I took it seriously and I reported it to the police," Mayor Amer Ghalib told the outlet. "I have been receiving many threats, but never took any of them as serious. He sent his threat to me through Facebook, then he immediately blocked me. That was another alarming and warning sign that made me act and report it to the police."He has not been charged in connection with the alleged threats..In April 2025, just over a year after his brother was murdered, Kai-Ji Adam Lo allegedly drove through a crowd of people at the Lapu Lapu Day festival in Vancouver. He has since been charged with 11 counts of murder. Dozens more were injured, many of whom are still recovering in hospital..Psychiatrists testify in hearing to determine whether Vancouver Filipino festival massacre suspect fit to stand trial.The Vancouver Police Department previously noted that Lo had a "significant history" of interactions with police and healthcare professionals related to mental health, and confirmed that he had "contact" with police on April 25, one day before the attack.Sgt. Steve Addison noted, however, that the interaction "was not criminal in nature," and "did not rise to the level where mental health intervention was required."On July 16, Lo appeared in Vancouver Provincial Court for a hearing to determine whether he is fit to stand trial.A pair of psychiatrists provided testimony during the two-day affair. Though the details they provided cannot be made public due to a sweeping publication ban ordered by Judge Reginald Harris, it can be revealed that one of those who testified was BC Forensic Psychiatric Hospital Medical Director Dr. Rakesh Lamba.The second day of proceedings ended with Harris announcing that all parties would reconvene in August to make their final arguments.
