Filipino street festival attack in Vancouver

I've been hearing pieces of information about the horrific murder at a Filipino street festival in Vancouver where a mental ill lunatic drove an SUV through a crown of people killing many and injuring many more.   

Today the police held a press conference and it was an update of the status of the victims. That's relevant but I'm more concerned with the offender. The one who viciously murdered all those innocent people. What the hell happened? 

This morning's report on the radio was talking about other violent murders involving people with mental health issues who were deemed not criminally responsible - NCR. They mentioned the horrible decision in BC to close Riverview. That was Gordon Campbell. 

The Associated Press is reporting that a mother, father and daughter were killed in the senseless tragedy while their 16 year old son stayed home to do homework. Another mother, father and daughter were killed. They were from Colombia. 

CTV is reporting that "Kai-ji Adam Lo, the man facing multiple murder charges in the attack at Vancouver’s Lapu Lapu festival, was under the care of a mental health team and on leave from hospital when he allegedly drove an SUV into the crowd."

This is just so wrong. Dimsum Daily is reporting that Lo's mental health began to deteriorate after his brother was murdered last year. 

Vancouver is Awesome is reporting that "Dwight William Kematch is charged with second-degree murder in the death of Alexander Lo, brother of Kai-Ji Adam Lo, now facing multiple murder charges following Saturday's deadly Filipino festival attack."

"In 2024, Kai-Ji Adam Lo launched a GoFundMe for his late brother's funeral costs. 'It pains me deeply to put these words down, but my brother has been taken from us in a senseless act of violence, something we never saw coming,' the GoFundMe page reads." That doesn't sound NCR to me.
