Keith Sampson, 29, of South Easton, was ordered jailed without bail until sentencing in February. The verdict was delivered late this afternoon in Taunton Superior Court. The victim, a Norton woman who is now 18, but was 15 at the time of the alleged incidents, said she and Sampson had a four-month sexual relationship beginning in November 2004 with a tryst in a motel in Germany where they were staying for a dance competition. Sampson was charged with two counts of statutory rape and had pleaded innocent. It is unlawful in Massachusetts to engage in sex with a person under 16. Sampson was found guilty in connection with an incident in January 2005 at the Taunton Holiday Inn. He was found innocent of the second charge of statutory rape, which prosecutors alleged occurred later at the victim's home. Sampson, who had no prior criminal record of sex offenses, had been free on bail in the case until he was arrested in Easton about a week ago for allegedly having sex with another 15-year-old student he met at a dance studio he owns in Johnston, R.I. A complete report will appear Friday in The Sun Chronicle. - By David Linton
