Vancouver Authorities Should Have Known Festival Attacker Posed Threat, Lawsuit Says

In the weeks before a deadly attack at a Vancouver Filipino festival, suspect Adam Kai-Ji Lo asked to have his antipsychotic medication reduced, even as his mental health was deteriorating, a B.C. Supreme Court lawsuit says.

The proposed class-action civil suit filed Thursday by a survivor of the attack says Lo’s psychiatrist was concerned during a meeting on April 11 that his patient’s mental health was deteriorating, that his delusions were increasing and his antipsychotic medication was insufficient.
