For many months, U.S. Postal inspectors investigated the matter, and a number of other related thefts of various valuables on the line from the locked pouches, before finally arresting Postmaster John Gatlin of the Myersville Station near today's Jeffrey City, Wyoming, along with his wife Stella. The trials of the couple in Laramie City went on into the Fall of 1893, when charges against John Gatlin were finally dropped, after Stella Gatlin confessed to stealing the items, due to what she claimed to be her illness of kleptomania. Her affidavit stated that she had struggled for years to overcome the mania, while keeping it a secret from her husband. On November 25, 1893, the jury found Mrs. Gatlin guilty. Two days later, she was taken to the Laramie Prison, where she was registered as Prisoner #150, the first woman to be imprisoned there after being convicted of a federal crime in Wyoming. She was released early in December 1894, based on her "good conduct", and following her departure, prison officials added a special new wing exclusively for women, with individual cells and a toilet.
