More than 20 years after Nadia Iverson’s body was found at a construction site with a gunshot wound to the head, a former Las Vegas police officer has been charged with raping and killing her. Records show Reno police arrested Sewall on Jan. 11. Metro said he was being moved to Clark County Detention Center. Sewall faces one count of murder with a deadly weapon and two counts of sexual assault with a deadly weapon. A criminal complaint shows prosecutors accused Sewall of raping and killing 20-year-old Iverson around May 8, 1997. Construction workers found her body in an apartment they were renovating at 1226 Reed Place, near Washington Avenue and Martin Luther King Boulevard.
