An 11-year-old boy was among those injured when a car ploughed into pedestrians outside a Las Vegas casino.
A witness said that he was trapped under the front of the vehicle before being ejected when the driver accelerated.
The witness told AP: "You could see the people literally flying off. And she had one little boy trapped underneath the front side of the vehicle. And she came to a stop and she accelerated again and it's a front wheel drive car and he shot out to the side. And you could see him eject to the front of the vehicle."
An adult was killed and at least 30 others, some visitors from Montreal, Canada, were injured. Six were in a critical but stable condition, police said.
The woman suspected of ploughing into pedestrians, killing one and injuring 36 others, had a three-year-old child in the car at the time, police said.
The woman, described as black and in her 20s, is in detention and is expected to be charged later today, Las Vegas police officer, Dan McGrath added.
The child was unharmed in the incident.
Based on the evidence and information from our fatal investigators, at this point we are treating this as an intentional act. She is in the detention centre right now, she is speaking to detectives. I expect her to be charged within the next few hours.
McGrath added that the 1996 Oldsmobile four-door car hit pedestrians as it mounted the sidewalk two to three times.
