A driver veered onto a crowded sidewalk several times on the Las Vegas Strip, injuring more than 30 people in what authorities described as an "intentional" act. At least one person was killed and 37 others injured near the Paris Las Vegas Hotel on Sunday night, authorities said. Witnesses said the woman was driving down Las Vegas Boulevard before her car jumped onto the sidewalk and started striking pedestrians. Police arrested the driver, and she is undergoing tests for alcohol and controlled substances. A 3-year-old in the car with her was unharmed. Authorities ruled out terrorism but said an initial investigation showed the driver did it deliberately.
