Police say a car drove into a crowd on the Las Vegas Strip late Sunday.
KTNV reports a woman named Jessica Valenzuela died and at least 36 were injured.
"We're not 100 percent ruling out the possibility of terrorism. The intentional act that occurred on the boulevard is going to be, is going to be very hard for us to explain," Las Vegas Sheriff Joseph Lombardo said.
Police arrested 24-year-old Lakeisha Holloway of Oregon in connection with the deadly crash. She's expected to be charged with one count of murder.
Authorities say Holloway had a 3-year-old child in the car at the time of the incident. The child was uninjured.
Crash survivor Anthony Hamel told KTNV: "There's people down there who really had, like, big problems. I saw some people. ... I'm 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.
