Cheri Spottke with the Westminster Police Department said the conditions of those shot are unknown. She confirmed that the suspect “fled the scene” and the search is underway.

Westminster police tweeted the vehicle of interest is a black Toyota 4-door, with Colorado license plate NPQ 091. Occupants should be considered armed. Call 911 immediately.

Police have cordoned off the parking lot of the Comfort Dental office as well as the neighboring parking lot of the Cedarwood Square Office Complex. The Children’s Dentistry office is located in a building in that complex.

Copter4 flew over the scene outside Children’s Dentistry where police cruisers were parked on the street surrounding the parking lot.

Several officers were seen collecting evidence from the parking lot and the entrance to the office building. There was a silver SUV with the rear passenger door open in the middle of the parking lot, not in a parking space.

There were several small orange cones and yellow markers with numbers on the ground. Those typically mark where evidence, including bullets, has been found.

It is unclear what happened leading up to the shooting.

Drivers are urged to avoid the area during the investigation. Police have blocked off 80th Avenue at the intersection.

Comfort Dental told CBS4 that everyone inside that dental office is unharmed.
