The Portland woman accused of driving into dozens of people and killing one in Las Vegas may have fallen asleep at the wheel, her cousin said Monday. Lakeisha Holloway, 24, is suspected of swerving onto a Las Vegas sidewalk Sunday evening. Based on video footage, Clark County Sheriff Joseph Lombardo said it appeared that Holloway intentionally veered into pedestrians, but the family disputes that account. Holloway works a lot and sleeps little, said her cousin, LaShay Hardaway. Taking care of her 3-year-old daughter and managing her fashion projects could have taken a toll, Hardaway said.
