UPDATE 2-Imposter who said he was missing Illinois boy charged by U.S. prosecutors

Federal prosecutors on Friday charged a 23-year-old former convict with making false statements after he claimed to be Illinois teen Timmothy Pitzen, who went missing in 2011 after his mother committed suicide, a U.S. Attorney said. Brian Michael Rini was charged with lying to federal agents after he appeared on Wednesday in Newport, Kentucky, outside Cincinnati on Wednesday and claimed he was 14-year-old Pitzen. He told them he had escaped from an eight-year ordeal at the hands of sex traffickers. Pitzen was last seen when he was 6 years old.

Rini's claim was debunked on Thursday after DNA test results conducted at the Cincinnati Children's Hospital confirmed he was not Pitzen. "Law enforcement confronted him with the DNA results, and at that point the person immediately stated that he was not Timmothy Pitzen, and of course law enforcement knew by virtue of the DNA analysis that he was in fact Brian Rini," said U.S. Attorney Benjamin Glassman during a briefing with reporters.

Rini appeared in federal court on Friday morning and is being held without bail until his detention hearing on Tuesday. He faces up to eight years in prison if found guilty, Glassman said. Rini's lawyer, Karen Savir, did not immediately return calls seeking comment on the charges against her client.

Rini had twice before claimed to be a child sex trafficking victim, according to federal prosecutors. He was released from Ohio's Belmont Correctional Institution on March 7 where he had been serving 14 months for burglary and vandalism, according to public records. "False reports like this can be painful to the families of missing children and also divert law enforcement resources in order to investigate these untruthful claims," said Herb Stapleton, acting special agent in charge for the Federal Bureau of Investigation in Cincinnati.

Pitzen was last seen in May 2011 with his mother, who pulled him out of school in Aurora, Illinois, a far-west suburb of Chicago, took him on a trip to a zoo and a water park, and then committed suicide in a motel room, leaving behind a cryptic note on her son's whereabouts. "Tim is somewhere safe with people who love him and will care for him," she wrote in the note, according to reports by ABC7 Chicago. "You will never find him."
