Joseph Martin, a 27-year-old married father of two from Sound Beach told his wife, Jennifer that he was taking a troubled young girl into their home.  He was arrested Friday at the Port Authority Bus Terminal in Manhattan, where he had gone to pick up a 12 year old girl, known only as Jane Doe of Columbus, Ohio.  Martin was remanded to Columbus, Ohio, yesterday to face federal charges that he used the Internet to try to lure the girl to him home for sex.  He sent the girl $81 for a bus ticket in a package shipped via UPS.  When the girl's father became suspicious and opened it, he contacted authorities.  Martin is being held without bail and the question of bail has been left to the federal judge in Ohio.  He is charged with attempting to kidnap a minor, attempting to transport an individual under 18 in interstate commerce for sexual activity and using a computer to induce a minor to engage in prohibited sexual activity.  He faces up to 5 1/2 years in prison if convicted, under federal guidelines.
