A security supervisor at Newark Liberty International Airport has been accused of using the identity of a New York man murdered 20 years ago to live and work in the United States, according to a report from USA Today.

Nigerian native Bimbo Olumuyiwa Oyewole, 54, was arrested at his home in Elizabeth, N.J. Authorities say that he has been in the U.S. illegally since 1989, and he had assumed the identity of Jerry Thomas, who was slain in Queens in 1992, according to the report. 

Oyewole worked for several private security contractors over the past two decades and passed background checks, including those by the New Jersey state police and U.S. Customs and Border Protection. His current employer, FJC Security Services, has held the contract since 2003, the report states.

Oyewole was in charge of about 30 guards at the Newark airport, which has been singled out by the TSA for several high-profile security breaches in a recent report.

The TSA says that it is reviewing the Port Authority of New York and New Jersey's procedures for validating employee and contractor documents.
