VANCOUVER, British Columbia — As members of the Le family headed out the door to enjoy music, food and camaraderie at a Filipino heritage festival in Vancouver, British Columbia, their 16-year-old son decided to instead stay home to finish homework.

Then news began arriving of a car plowing through the crowd.

The teen's father, Richard Le; his stepmother, Linh Hoang; and his 5-year-old sister, Katie Le, were among 11 people killed, said Richard Le's brother, Toan Le, in the world's latest vehicle ramming attack.

The teenage boy is in a state of shock, Le said. His sister Katie Le was nearing graduation from kindergarten and was described as a vibrant and joyful child in a GoFundMe page posted by Toan Le.

The black Audi SUV sped down a closed, food-truck-lined street Saturday evening and struck people attending the Lapu-Lapu Day festival, which celebrates Datu Lapu-Lapu, an Indigenous chieftain who stood up to Spanish explorers in the 16th century.

Thirty-two people were hurt. Seven were in critical condition and three were in serious condition at hospitals Monday, Vancouver police spokesman Steve Addison said.

Those killed include nine females and two males ranging in age from 5 to 65, according to Addison. All of them lived in the Vancouver metropolitan area, he said.

Mourners, including Canadian Prime Minister Mark Carney, remembered the dead at vigils before Monday's national election.

The crash came just two days before another vehicle smashed through a building in a town outside of Springfield, Illinois, during an after-school program, killing four children and injuring several others, police said.

A 'significant history' of interactions with police

Kai-Ji Adam Lo, 30, was charged with eight counts of second-degree murder in a video appearance before a judge Sunday, said Damienne Darby, spokeswoman for British Columbia prosecutors. Lo has not yet entered a plea.

A woman who answered the phone Monday at the home of Lo's mother, Lisa Lo, said that the mother was too distraught to speak to a reporter.

Investigators said more charges were possible. They said Lo had a history of mental health issues.

Interim Police Chief Steve Rai said there was no indication of a motive but that the suspect has "a significant history of interactions with police and health care professionals related to mental health."

The Associated Press could not immediately reach an attorney representing Lo.

Online records showed that Vancouver Provincial Court issued a publication ban barring the release of details about the legal case against Lo. Such bans are common in Canada to protect the rights of the accused to a fair trial as well as the privacy of crime victims.

Lo's brother, 31-year-old Alexander Lo, was the victim of a homicide at his home last year. Kai-ji Lo started an online fundraising effort, since deleted, seeking donations to bury his brother.

Screaming and bodies hitting a vehicle

Noel Johansen was searching for dessert at the festival with his wife Jenifer Darbellay, an artist, and their two children, ages 7 and 15, when the attack happened.

"It hit us before we knew. I was falling in slow motion trying to save my head from smashing in the pavement," Johansen said. "It's like a giant tidal wave."

Darbellay, 50, was killed, while the rest of the family survived. Johansen described her as selfless, creative and empathetic.

Johansen said the day before she was killed, the couple was talking about politics and the many situations in which people seek revenge toward the person who hurt them.

He said she told him: "That's the whole problem. We need to forgive the perpetrators of the crimes that are committed against us."

Johansen said that he's trying to honor that philosophy.

Hours before the attack, Makayla Bailey saw her friend Kira Salim, a teacher and school counselor, for the first time in a while and Salim had apologized for not being out and about more.

"I told them, 'It's OK it's been crappy out, the weather sucks, summer's coming so I'm sure we'll see each other a lot more,'" Bailey said, recalling in an interview Salim's drag king performances that audiences loved.

"I didn't think it would be the last conversation we would ever have," said Bailey.

Salim was among those killed in the attack, according to the New Westminster School District, where Salim worked.

"This was intended to be a safe, fun, family-friendly community block party for people to celebrate their community and culture," Addison said. "The actions of one person stole that away from them."
