A 29-year-old District man who was convicted on weapons charges under his brother’s name was sentenced to 15 years in prison after authorities untangled his true identity, according to Prince George’s County State’s Attorneys office.

When Jonathan Murray was arrested in 2007 on a charge of illegally possessing a firearm, he falsely told police that he was Darryl Murray, his brother who has a clean record, authorities said. At the May 2008 trial, Jonathan Murray continued to pretend that he was Darryl Murray. The jury took 45 minutes to return a guilty verdict.
