Anthony J. Domico, a former contractor hired to check the backgrounds of U.S. government workers, filed a 2006 report with the results of an investigation.
There was just one snag: A person he claimed to have interviewed had been dead for more than a decade. Domico, who had worked for contractors CACI International Inc. (CACI) and Systems Application & Technologies Inc., found himself the subject of a federal probe.
Domico is among 20 investigators who have pleaded guilty or have been convicted of falsifying such reports since 2006. Half of them worked for companies such as Altegrity Inc., which performed a background check on national-security contractor Edward Snowden. The cases may represent a fraction of the fabrications in a government vetting process with little oversight, according to lawmakers and U.S. watchdog officials.
