Troby inspected the paper and arrested the murderer from the office within minutes. How?

• Detective Troby was soon after dismissed from the force, because the suspects he arrested kept being released by the judge due to a complete lack of evidence. – Gilles 'SO- stop being evil' Oct 13 '14 at 10:04
• @Gilles: Don't you read newspapers? The murderer Noel confessed during the interrogation and handed over the murder weapon, and other evidences to the inspector Troby. Judge sentenced Noel for lifetime imprisonment. Troby got promotion and now happily having a doughnut in his cabin :P – AeJey Oct 13 '14 at 10:18
