Stephen Paddock's work history included stints with the U.S. Post Office, the Internal Revenue Service (IRS) and the Department of Defense.
According to the Office of Personnel Management (OPM), which tracks government employee work history, the former accountant spent a total of about a decade on the government's payroll.
Paddock's government history began in 1975 with temporary roles at the U.S. Postal Service.
In July, 1976 Paddock landed a letter carrier position where he spent two years before moving on to the Internal Revenue Service as an Internal Revenue Agent. While it remains unclear in which division of the IRS Paddock worked, a spokesperson with OPM says he spent 6 years with the IRS before he ended up in the auditing department of the Defense Contract Audit Agency.
According to its website, the Defense Contract Audit Agency provides audit and financial advisory services to the Department of Defense (DoD) and other federal entities responsible for acquisition and contract administration.
