Two-month-old Miowne Obote died at Sunrise Children’s Hospital in Las Vegas on July 22, 2010. Born extremely premature, Miowne’s death was ruled a homicide by the Clark County Coroner’s Office after investigators determined she suffered severe bleeding and a fatal lack of oxygen to the brain when an umbilical catheter was severed.

The coroner’s homicide finding indicates the fatal injury involved an interaction between two people, though it does not by itself assert intent. At the time of the initial investigation the Las Vegas Metropolitan Police Department had not filed charges, and no suspects were publicly identified or taken into custody; the case remained active as authorities investigated how the catheter was severed.

Who knew Miowne or was at Sunrise Children’s Hospital in July 2010 and might have information about that day?
