Two people were killed and seven were injured after an SUV crashed into two Douglas County sheriff's patrol cars south of Denver this morning.
Two deputies are among those hurt but the State Patrol says their injuries are minor.
The four surviving passengers in the Honda Passport had serious injuries and the driver had moderate injuries.
State Patrol Master Trooper Ron Watkins says investigators believe alcohol, drugs or both were involved.
Watkins says the passengers who were killed were a man sitting in the front passenger's seat and a woman who was sitting in his lap.
Watkins says the patrol cars had pulled over a vehicle for a traffic violation and one of the cruisers was part way in the right-hand traffic lane on C-470 when it was hit by the Honda at about 2 A.M.
He says the Honda pushed first cruiser hit the second, which spun around and collided with the Honda.
The car the deputies had pulled over was not hit.
