She drove from the Las Vegas strip onto the sidewalk and didn't stop. One person was killed and the driver is in custody.
FOX's Gurnal Scott has the latest:
The woman's name has not been officially released, but Vegas police say it seems the act was done with intent. But Lt. Peter Boffelli says they want to be absolutely certain before charges are filed.
(Boffelli) "All the testing abilities that we're doing on this individual is to ensure that we're doing the proper investigation, whether it was an impairment or anything to that matter."
In addition to the person killed, police say at least 30 others were hurt. The driver had a child in the car with her. Video surveillance angles are also being looked at, but authorities seem certain this was not a terrorist act.
