New details have been released in an alleged Sioux Falls human trafficking case.

Police say Jonathan Cohen, 36, of Sioux Falls, was arrested Tuesday after an argument with the 16-year-old female victim who had been staying at his residence. They say Cohen met the victim, reported as a runaway in August, through an online dating site.  Investigators found the victim traveled from Georgia to Sioux Falls in September and stayed at Cohen’s residence for four days. They say the victim had a sexual relationship with Cohen during that time. She then returned to Georgia.

Authorities say that Cohen recontacted the victim through text message once she had returned to Georgia, and arranged for her to return to Sioux Falls on Oct. 3. They say she stayed at his residence and that the two continued to have a sexual relationship.

The case came to law enforcement’s attention on Oct. 4, when the victim called 911 after an argument with Cohen. Police arrested him Tuesday evening.

Cohen, a physician at Sanford Health, is charged with human trafficking, promoting prostitution, sexual exploitation of a minor, and solicitation of a minor.

He is expected to be in court this afternoon.
