POLICE have launched a massive hunt for a shooter after four people, including two children, were gunned down outside dentist office in Westminster, Colorado.
The victims were shot in the car park behind Comfort Dental before the suspect made off in a black Toyota, cops said.
They said two adults and two children were rushed to hospital but their conditions remain unknown.
Officers are urging members of the public not to engage with anyone seen inside the vehicle as they could be “armed and dangerous”.
Cops released an image similar to the car they are searching for on Twitter as well as the make, model and license plate number.
Westminster Police Department spokeswoman Cheri Spottke said the man is at large but they do not believe he is still in the area.
