  The driver, Kai-Ji Adam Lo (Chinese: 羅凱基), a 30-year-old individual residing in Vancouver, was apprehended by bystanders after attempting to flee, and taken into custody by police. He is believed to have acted alone and was the sole occupant of the car. The Vancouver Police confirmed that Lo has a significant history of interactions with police and healthcare professionals "related to mental health", but no prior criminal record. The police rejected terrorism as a motive.
  
  On January 28, 2024, Lo's 31-year-old older brother, Alexander, had been found dead in a Kensington-Cedar Cottage area home in East Vancouver. A suspect was charged with second-degree murder in connection to the killing, pleading not guilty in October 2024, with trial pending as of April 2025.
  
  Lo's mother attempted suicide a few months after Alexander's death, and remained in hospital for a month.
  
  The day before the attack, police interacted with Lo. As of April 27, the only detail about the interaction released by police was that they decided that a hospital visit was not required. Hours before the attack, a family member had contacted a psychiatric ward about Lo's deteriorating mental health. He appeared to suffer from delusions and paranoia. It is currently unknown whether any action was taken. Vancouver Coastal Health confirmed that at the time of the attack, Lo was under the care of a mental health team and on extended leave from hospital in accordance with the Mental Health Act. They also said there was no indication Lo was a public safety risk.
  
  On May 2, 2025, a judge ordered Lo to undergo a mental health assessment.
