The woman accused of killing one person and injuring multiple others on the Las Vegas Strip after driving onto a sidewalk was due to appear in court on Thursday.
However, Lakeisha Holloway was not there and a judge has ordered a competency hearing at 9 a.m. on March 11.
The 24-year-old woman was so unruly during her last scheduled court appearance in early February that she could not be brought into the courtroom.
She could be heard screaming by those inside the courtroom.
The Strip crash suspect is facing a total of 71 charges. If convicted, she could be sentenced to more than 1,000 years in prison.
Holloway's 3-year-old daughter was in the car with her at the time of the crash on Dec. 20.
The crash killed 32-year-old Jessica Valenzuela of Arizona.
The crash happened in the area between Planet Hollywood and the Paris hotel-casino on Las Vegas Boulevard.
