A Quincy District Court judge ruled today that even if he accepted Norman Barnes's version of how a Dorchester 15-year-old came to spend two weeks with him, having nightly sex with strange men, he's an immediate threat to the girl and society, and denied his request to be released on bail while awaiting trial.

Barnes's attorney, Joanna Sandman, argued the girl was a troubled kid who conccoted a story about being kidnapped and forced into prostitution to account for the two weeks she voluntarily spent with Barnes in motels in Dorchester, Danvers and Quincy.

Sandman said the girl had several chances - including one day she claimed Barnes let her return to classes at Dorchester High School - to alert authorities and yet never did and that investigators presented no evidence the girl was physically harmed or that she actually had sex with up to eight men a night. Sandman said Barnes, 28, is a loving father of four who worked fulltime as a car salesman and posed no threat to witnesses.

But Judge Mark Coven said that even if Barnes's version were true, he would be guilty of making money from prostitution - and statutory rape for having sex with her himself.

Norfolk County Assistant District Attorney Erin Murphy and State Trooper David McSweeney painted a far darker picture of the girl's two weeks with Barnes, and described a girl so terrified of the man she knew as "Shizz" that he even let her go to school at Dorchester High School one day, confident she would do whatever he said. At one point, McSweeney said, a friend came up to her at school and told her Shizz was waiting for her outside - and she left school immediately.

McSweeney said the teen and a friend were walking around the Ruggles Street area on May 9 when a guy stopped his Camry and began talking to the friend. The two then got in his car. He drove the friend home, but instead of driving the alleged victim home, told her to get into the front and drove her to the Ramada Inn on Morrissey Boulevard in Dorchester. "He made a comment they were going to make some money," McSweeney said, adding Barnes made sure to show the girl a folding knife he had.

McSweeney said Barnes gave her lingerie, posed her in provocative poses on a bed and then posted them to the Boston female escort section of backpage.com. He gave her a script in which she would answer phone calls as "Maria" and offer to have sex with the callers $100 for 30 minutes, $150 for an hour. McSweeney said she had sex with three strangers that night, staying in the bathroom for each session - and taking all of the money. The duo drove up to Danvers, where they stayed in two other motels, repeating the process, and then drove to Quincy and the Best Western off the Neponset River Bridge.

There, McSweeney and Trooper Gail Bettinger said, Barnes left the girl alone for a while - time she used to go down to the lobby and use a hotel PC to log into Facebook and contact her aunt and plead for her to come get her. The aunt and uncle drove across the Neponset River bridge, pulled into the hotel parking lot and, when they saw Bettinger working a detail, yelled to her for help.
