According to the Douglas County Sheriff's Twitter account, 'multiple deputies' from a sheriff's office in suburban Denver have been wounded.
A major highway south of the city has been shut down because of the active situation. Residents in the vicinity are being asked to shelter in place and avoid windows and exterior doors.
Authorities say deputies were responding to a domestic disturbance call that resulted in shots fired. Five deputies were shot by the suspect, with one deputy killed in the exchange. Two other people who were near the scene were also shot. Officials say they believe the suspect was killed and is no longer a threat.
