William and Lily Marti were sentenced to 7 years in prison yesterday for kidnapping, molesting and sexually abusing street children in India.  They were also ordered to pay $106 to each of three girls.  The couple, of Steinhausen, was arrested in 2000 and charged with taking nude photographs of poor street children who approached them for food and money.  They have been in jail since.  The time served, more than two years, will count toward their term.  Police arrested them at an upscale Bombay resort in December 2000 while they allegedly filmed 8 & 9 year old naked girls.  The girls were among 21 witnesses who testified at the monthlong trial.
