A Denver Police Department spokesperson said the department received calls of shots fired just after 4 p.m. He said the three wounded persons were transported to the hospital in critical condition.

The spokesperson confirmed the suspect is at large and made clear that police do not know “if there was one shooter or more than one.”

Colorado has universal background checks and a ban on “high-capacity” magazines, both of which were passed in early 2013.
