 Good evening, I'm Anna Erickson in the WBT News Center. A Charlotte police officer dies this afternoon from taking his own life. CMPD says K-9 officer Brent Simpson died from a self-inflicted gunshot wound. At 12.37 p.m., CMPD put out an alert for an officer-involved shooting over in the Steel Creek area. That alert from CMPD immediately invoked memories of what happened just a couple short months ago where four law enforcement officers were shot and killed.
