One of the sergeants then shot and wounded the suspect.   The girlfriend and a 65-year-old member of the suspect’s family, who suffered a non-life-threatening gunshot wound, were taken to a hospital.  The suspect suffered life-threatening injuries and was taken to a hospital.  The sergeant who shot the suspect is an 18-year police veteran. He will be placed on standard administrative duty during an investigation.
