Police say those in the world's oldest profession are finding Craigslist.org to be a suitable alternative to street corners.

The changing of venues is keeping Myrtle Beach police detectives busy conducting undercover sting operations.

Just this week, police arrested a Midlands man and woman they say were offering sex in a Myrtle Beach hotel via the popular website Craigslist.

After responding to an ad, detectives made an appointment with Heather Michelle Armstrong, 23, and went to meet her at a hotel room, according to an incident report.

Police arrested her and charged her with prostitution and possession of a suspended driver's license. She was taken to jail and released on a $1,500 bond.

A man who police say conspired with Armstrong was also booked on a prostitution charge, as well as for operating without a business license. Tyrone Leon Spearman, 33, was released on a $938 bond.

The latest arrests are just a couple in a string of arrests since November 2008. A preliminary search by NewsChannel 15 of Myrtle Beach incident reports shows police have conducted close to ten similar operations.

Myrtle Beach Police Captain David Knipes refused to comment on any of the investigations citing the confidentiality of tactics used during the sting operations. He said releasing that to the public might hurt the success of the investigation.

WPDE checked out Craigslist on Wednesday and found dozens of ads where women listed numbers to call and rates for what they promised to be "good times."

When we reached some of the women by phone, we were told what their online ads meant.

"It is $200 for an outcall (where a woman would go to the client), $175 for incall (where the client would go to the woman). We're located in central Myrtle Beach. We have blondes, brunettes, redheads," the woman explained.

One of our next questions was, "Can this buy somebody sex?"

"Yes," the woman on the other line responded.

When we identified ourselves and pressed the woman on the legality of such services, she said she misunderstood the question.

"I honestly did not hear that's what you said."

We called another woman whose ad described a cougar -- an older woman in her 50s looking for younger men.

From the start of the conversation, the "cougar" was cautious, asking questions like, 'Are you affiliated with law enforcement?'

She went on to explain her service included companionship, but would cost someone $200 per hour. What transpired aside from the companionship, she said, was up to two consenting adults -- but that the money would be meant for the companionship, not the possible sex.

"No money is exchanged for sexual favors, because that's illegal, and I don't do anything illegal," she said.

After identifying ourselves as being with NewsChannel 15, the woman launched a lengthy rant against how police are monitoring Craigslist.

"They (police) have entrapped a lot of girls out there as far as like the sting they had going," she explained.

After Chicago police sued Craigslist over the prostitution issue earlier this month, the website issued this statement: "Misuse of Craigslist to facilitate criminal activity is unacceptable, and we continue to work diligently to prevent it."
