Seeing as the man Jason Pierce was not in his room at the end of Aron's shift of interrogations he decided he might as well head back to the security offices and put all the paperwork on to the terminals. Taking the stairs he used his key card to enter the complex. But before he could make another two steps, an officer grabbed him and told him the terrible news. A lab technician, the officer guarding evidence killed, and another officer missing.
But then it hit him, he had a revelation:
Who ever entered the security complex used a pass card, and I could check records to see whose pass card was used. But I already know that its the one of the missing officer. [censored]. We put the Vault on lockdown and search all non-security personnel rooms, starting with high priority targets and will find the pass card and they'll be guilty of all the murders.
He was about to take off to Security Chief's room when, he got a shout out over the radio from the Chief telling him to get his scrawny ass down there now or he was out of a job. Moving through the offices he burst through the door, without letting anyone else speak he explained the situation:
"Chief, sir, whoever entered the security complex and took evidence from the locker and killed the two other men must have the other missing officer's pass card. If we put the Vault on lockdown and search all rooms starting with priority targets, we'll find the person with the passcard and convict them of all the murder's" he then quickly added "Sir" to the end of his small speech knowing that even though his idea was good being disrespectful would still make him liable to get put in the detention center and not get to reap the rewards of solving a huge case.
