(Newser) – An Ohio man who caused fresh heartbreak for the family of a long-missing boy has been sentenced to 2 years in prison for aggravated identity theft. Brian Rini, now 25, was 23 years old when he claimed to be 14-year-old Timmothy Pitzen, an Illinois boy who has been missing since his mother killed herself in 2011. He told authorities he had escaped from kidnappers who sexually abused him. At a sentencing hearing Tuesday, prosecutors told Rini he had caused "an enormous amount of unnecessary pain" to the missing boy's family, the Cincinnati Enquirer reports. "I just want to say I'm sorry for what I've done, and I wish I could take it back but I can't." said Rini, who has a history of mental health issues. "I'm sorry to the family." Two other charges against him were dismissed.
