Police have named the suspect who allegedly drove into pedestrians on the Las Vegas Strip, killing one person.
Lakeisha Holloway, 24, is expected to face murder and other charges in connection with Sunday's incident.
Police said Holloway had been homeless and living in a car with her three-year-old child - who was apparently in the car at the time of the crash.
Clark County Sheriff Joe Lombardo told reporters that Holloway may have been under the influence of a "stimulant" and had just had an argument with the child's father prior to the crash.
