The first happened around 7:14 p.m. at E. Celeste Avenue and Torrey Pines Drive.
According to the Las Vegas Metropolitan Police Department, it involved a pedestrian and vehicle.

According to police, 75-year-old Roland Bame was using a marked crosswalk on Torrey Pines when he was hit by an oncoming Honda CR-V.
The 32-year-old driver reportedly did not see Bame crossing at the time, and therefore did not stop in time before striking him.
Investigators do not believe impairment was a factor.
Bame's injuries are considered life threatening.

The second collision took place at Jones Boulevard and Rochelle Avenue.
Police responded around 8:02 p.m. and found that a vehicle and pedestrian were involved.
