In October 2006, Mateen began working as a recruit for the Florida Department of Corrections and was assigned to Martin Correctional Institution. In a letter explaining his youth record as part of his successful application, Mateen explained the incident when he was arrested at school at the age of fourteen. After the shooting at Virginia Tech in April 2007, Mateen suggested in a training course for correctional officers that he would bring a gun to class. P.H. Skipper, who was the institution`s supervisor, wrote that “given the tragic events that occurred to the Virginia Tech officer, Mateen`s request to bring a firearm to class is extremely troubling at best.” A few days later, on April 27, 2007, Mateen was “unintentionally” released from the program and never became a licensed correctional officer.
