This is quite scary and sad. From MPD:
The Metropolitan Police Department is currently investigating a police involved shooting of a dog that occurred in the 3400 block of Quebec Street, NW.
On Sunday, December 6, 2009 at approximately 5:30 pm, members of the Second District responded to the 3400 block of Quebec Street, NW, in reference to a call for a victim who had been bitten by a dog.
Prior to police arriving, a concerned witness heard the victim screaming for help. He managed to pull the dog, a male pit bull, off the victim, subdued the dog and placed the animal in a cage.
In addition to police, personnel from DC Animal Control and DC Fire and Emergency Medical Services responded to the scene. The victim, an adult female, was admitted to a local hospital and is currently in stable condition.
During the investigation of the incident, the dog reportedly became aggressive and got out of the cage. Animal Control employees made several unsuccessful attempts to secure the dog. The dog then charged towards one of the responding officers. Fearing imminent danger for his safety and the safety of others, the officer fired his service weapon, striking and injuring the dog.
Animal Control officers were then able to secure the dog, which has subsequently been euthanized.
The member who fired his weapon is a 39-year-old sergeant who has been with the department for 12 years.
“This is a tragic incident,” said Police Chief Cathy L. Lanier. “I commend the man, who put his own life in danger and stepped in to assist the victim in this violent dog attack. I also want to recognize the sergeant who stopped the dog from attacking anyone else.”
