Waltham man pleads not guilty to raping 6-year-old boy

A Waltham man twice convicted of assaulting children pleaded not guilty yesterday to a charge of raping a young boy in a Hyannis hotel last year.

John Cox, 39, of 15 Prospect Street Ave., who was arraigned in Barnstable District Court, is accused of assaulting a 6-year-old Connecticut boy in a swimming pool locker room more than a year ago.

Brian Glenny, first assistant district attorney for Barnstable County, said Cox was charged with rape of a child and lewd, wanton and lascivious conduct.

Cox, a registered sex offender, was arrested Friday after Barnstable Police told police in Waltham that DNA evidence collected more than a year ago linked Cox to the crime scene.

"Barnstable (Police) came up here and we arrested him on their probable cause (case) for rape of a child," Waltham Police Sgt. Tim King said yesterday. "Through the efforts of the Waltham Police keeping up with the sex offender registry board, we were able to help locate him."

Barnstable Police Sgt. Sean Sweeney said the assault occurred in May 2006. With the help of the state crime lab, investigators gathered forensic evidence in the hotel locker room/bathroom.

"John Cox was not staying at the hotel. He both resides and works (in Waltham)," Sweeney said.

According to the state sex offender registry board's Web site, Cox was convicted on one count of rape of a child with force in 1997. In 2001, he was convicted on one count of indecent assault and battery on a child under 14.

Cox was determined to be of high risk to re-offend and posed a public threat, according to the board.

"This guy is a Level 3 (sex offender), which is mostly likely to re-offend," Sweeney said. "The 6-year-old did give a description at the time, but the guy was from out of town."

Sweeney said after a yearlong investigation of the forensic evidence, a match was made to Cox.

"The state crime lab did a nice job," Sweeney said. "If it wasn't for that, one has to wonder if this guy would have ever eventually got caught down here."

Cox's bail was set at $50,000 cash, and he was ordered to return Oct. 19 for a probable cause hearing.
