PORTLAND, Ore. >> A federal grand jury has indicted eight Portland men accused of transporting women across state lines to engage in prostitution.

One of the alleged pimps is Mark Miles, who allegedly took Ivy Harris to Hawaii last spring. 

The 29-year-old Harris was killed during the visit and a Marine is awaiting trial on a murder charge. 

The indictments unsealed Monday stem from an FBI-led enforcement called "Operation Traffic Stop." 

Besides Hawaii, prosecutors say the prostitutes were taken to Alaska, Idaho, Minnesota and Nevada.

Also charged were: Steven Huffman, Jorge Ortega, Jermaine Hankins, Michael "Mackin Mike" Willis, DeShawne Howard, Samuel Howard and Camillio Carradine.
