SALEM -- The Civic Center in Salem looks like a nondescript building on the outside. It's the hub for city business that includes the police department.
"There's signs all over the Civic Center directing you to the police department," said Lt. Dave Okada.
Apparently those signs are not very visible. Two weeks ago, according to Okada, a detective on the street crimes unit posed as a "John" on line. He met a Portland woman who agreed to come to Salem and perform sex acts with the officers in exchange for money.
"The detectives were in touch with her, they directed her to the area," said Okada. "They gave her directions to an unmarked door here at the Salem Police Department."
That is where police arrested Smith. She missed several signs indicating she was at the actual police department. She walked by three uniformed officers.
"I've been doing this for a long time and I can tell you this is an unusual case for us," said Okada.
Safe to say Smith now knows the location of the Salem Police Department. She will be returning soon and it will not be for an unmarked door. Instead she will be looking for a door marked court where she will be facing charges of prostitution and promoting prostitution.
Salem police urged anyone involved in possible human sex trafficking to get help or call 911.
