Police say a car drove into a crowd on the Las Vegas Strip late Sunday.
KTNV reports one dead and at least 36 injured.
"Based on her movements in the vehicle, it appears to be an intentional act," Sheriff Joseph Lombardo said in a statement.
Authorities say the 20-year-old suspect had a 3-year-old child in the car at the time of the incident.
Crash survivor Anthony Hamel told KTNV: "There's people down there who really had, like, big problems. I saw some people. ... I wondering if they're good, how their life will be just because of this."
The incident happened outside the Planet Hollywood hotel, which hosted the Miss Universe pageant Sunday.
Investigators are still searching for a motive.
