SIOUX CITY — Two women accused of staging a bank robbery in Sioux City have each been sentenced to five years in prison. Heaven Zevenbergen, 19, and 18-year-old Angelica Perez were sentenced in separate hearings Wednesday. Both had pleaded guilty to second-degree theft. Prosecutors said Perez entered a Security National Bank branch at a Hy-Vee supermarket last August in a disguise, and warned Zevenbergen via a note that she was armed.
