Three men charged with soliciting sex from Boston Police officers posing as a young teenage girl have been ordered to stay away from all children while their cases are pending, Suffolk County District Attorney Daniel F. Conley said today.

JOHN CAPUTO (D.O.B. 2/10/48) of South Boston, DANIEL KLIM (D.O.B. 5/18/73) of Cambridge, and JOHN NGUYEN (D.O.B. 7/28/87) of Randolph were all arraigned in Dorchester District Court this morning on charges of soliciting sex for a fee and enticement of a child under 16 for their alleged efforts this weekend to engage in sexual activity with a person they believed to be a 15-year-old girl. All three posted $300 cash bail following their arrests Saturday and walked into court today.

Assistant District Attorney Gretchen Sherwood recommended that bail be set at $7,500 for Klim and Nguyen, and at $10,000 for Caputo, who had previously been charged with sex for a fee in 1998 and 2000. Both of those cases were continued without a finding, Sherwood said. Sherwood also recommended that the three be ordered to stay away from all children under 17 during the pendency of the case.

Judge Shannon Frison set bail at $7,500 cash for all three and imposed Sherwood’s recommended stay-away order.

“As repugnant as it is to most of us, the commercial sexual exploitation of children is very real,” Conley said. “It exists because of the demand illustrated here. Boston Police, Suffolk prosecutors, and law enforcement across New England are focusing on this issue like never before, and those who want to buy sex with children can count on more investigations like this one.”

The defendants were arrested separately throughout Friday afternoon and evening after allegedly soliciting sexual activity from Boston Police officers posing as a 15-year-old girl. After communicating online, each of the defendants allegedly made arrangements to meet that “girl” for the purposes of sexual activity. After arriving at various locations along Gallivan Boulevard in Dorchester, each of the three was taken into custody.

In 2006, Conley launched a program to divert juveniles arrested in sex-for-fee cases away from prosecution and toward social service providers. That program, known as Support to End Exploitation Now, has twice been named a Top 50 Innovative Government Program by a Harvard University think tank. Boston Police are a major partner in that multi-agency program. Conley has pushed for legislation that would expand his voluntary policies statewide.

Caputo is represented by attorney John Henneberry and will return to court on Dec. 7. Klim is represented by attorney Frank Camera and will return to court on Dec. 27. Nguyen is represented by attorney Pam Murphy and will return to court on Dec. 2.
