A St. Paul man accused of trafficking two female minors for commercial sex in Washington County was sentenced to 10 years in prison Thursday, July 7.

Joshua Carlisle, 25, pleaded guilty in March to promoting prostitution of an individual and trafficking a juvenile individual, both felony charges.

An investigation team made up of Washington County Sheriff's Office and police from Woodbury, Oakdale, Forest Lake, Stillwater, St. Paul and Minneapolis traced a Backpage.com posting that contained a video of a 14-year-old suspected trafficking victim to Carlisle's phone.

The girl's 17-year-old sister was reported as a runaway the same day officers discovered the video. She was later located in a St. Paul park wandering without shoes and apparently under the influence of drugs before she was transported to the hospital.

Investigators arrested Carlisle after tracking his cell phone in February.

"This case illustrates our community’s need to protect those in our community who are the most vulnerable, our youth," Washington County Attorney Pete Orput said in a statement Thursday. "We need to recognize that sex trafficking is no longer on the urban street corner, but in our own homes, urban and suburban, as a result of social media."
