A Vietnamese national convicted of attempting to murder a police officer walked free in American communities for over 15 years because his home country refused to accept him back.

Despite receiving a final deportation order in December 1997, confirmed by the Board of Immigration Appeals in May 1998, Nguyen remained in the United States.

Nguyen first entered through Honolulu, Hawaii, and was transferred from the Texas Department of Criminal Justice to ICE custody in March 2011 before his release three months later.
