Cops: 'Stoic' Vegas Driver Asked Valet to Call 911

The woman accused of intentionally steering her car into crowds on the sidewalk of Las Vegas Boulevard on Sunday has been identified as 24-year-old Lakeisha Holloway, who is believed to be from out of state and had been in Vegas for about a week, investigators say, possibly living in her car. Holloway is described as "stoic" in the aftermath, reports USA Today, and reportedly asked a valet to call 911 after describing her actions.

Police say she may have had an argument with the father of her 3-year-old daughter, who was in the vehicle; a drug expert at the scene further tells the AP that the suspect was on some type of "stimulant," though the Review-Journal reports that she wasn't exhibiting severe impairment, citing police sources. Formal charges are expected later Monday or early Tuesday, the DA tells USA Today. A 32-year-old Arizonan, Jessica Valenzuela, has been identified as the sole casualty thus far.
