 There's no guarantee nothing will happen, but there is a guarantee that if something does happen, that our officers will be there. CNPD today mourning the loss of another officer. A little over two months after that deadly ambush in East Charlotte that killed four cops, CNPD K-9 officer Brent Simpson has died, passed away from a self-inflicted gunshot wound. He'd been with the department 18 years, most recently assigned to the K-9 unit, also served in the U.S. Navy. Funeral arrangements have not been announced.
