A Montreal man celebrating his 21st birthday in Las Vegas was among the pedestrians struck by a car Sunday night on the Las Vegas Strip.

Anthony Hamel, who is from the off-island suburb of Delson, told a local TV station he was walking with his family when the vehicle veered onto the sidewalk.

He was treated for a knee injury and released, while his mother and other relatives suffered more serious injuries.

"I saw some people crouching and I'm wondering if they're good, how their life will be, just because of this," Hamel told a KTNV.

His cousin, Sébastien Hamel, who didn't go on the trip, said he was relieved to hear Anthony wasn't seriously hurt.

"At the moment I knew it, I text him. And he said he was fine so, it's OK," he told CBC News.

Police say one person was killed in the crash and five others are in critical but stable condition.

In total, 35 were people were injured.

She said some of the patients required a French translator and at least two of them, a man and a woman, are from the Montreal area.

"I'm sure that as they start to feel better that of course the investigators will come by and speak with them but right now we are more concerned with making sure they recover from their injuries," she said.

"We are treating this as an intentional act," said Lt. Dan McGrath of Las Vegas Police's homicide division.

On Monday, police identified the suspect in the crash as Lakeisha N. Holloway, 24, of Oregon.

She faces a charge of murder and is being held without bail, prosecutors say. District Attorney Steve Wolfson said he also is considering a slew of other charges.

"When a person drives a 2,000-pound-plus motor vehicle intentionally onto a sidewalk, killing and injuring scores of people, that's murder," Wolfson said.

Holloway had been homeless and living in her vehicle with her young child, the sheriff said.

"This is a huge tragedy that has happened on our Strip," police Lt. Peter Boffelli said.
