HOUSTON (KTRK) -- The Harris County Sheriff's Office took immediate action overnight after learning a jail insider reportedly wanted to get an autograph from the man accused of gunning down a deputy last week.Shannon Miles is locked up, charged with capital murder. He's accused of shooting Deputy Darren Goforth as the deputy filled his squad car with gas Friday night.Now, we've learned a nurse working inside the jail clinic was escorted out of the jail overnight and told not to return after co-workers apparently overheard her say she wanted Miles' autograph.Hard to understand why someone would want an accused officer-killer's signature, but nonetheless that's what we're told happened.The nurse works for an employment agency that supplies the jail with nurses and was immediately replaced.We're told she never got in contact with him and his movements in the jail are very controlled, but it's still concerning.This comes as Texas Senator John Cornyn reintroduced federal legislation Wednesday to stop the so-called "murderabilia" industry.Cornyn has tried and failed to introduce legislation to ban the sale of items linked to killers, but will reintroduce it later this month.The Stop the Sale of Murderabilia Act would prevent violent criminals from making money from their crimes and reputations. The bill would make it illegal for state or federal prisoners from knowingly mailing any item out of state to make money.Andy Kahan, a victims advocate with the city of Houston, joined Cornyn at a press conference Wednesday morning and has been pushing for a federal law for years.Senator Cornyn's office released this statement saying in part:"The sale of murderabilia sensationalizes violent crimes, hinders victims' healing process, and re-opens old wounds. It rewards those who peddle the goods of notoriously violent criminals."
