A St. Joseph man and woman have pleaded guilty in federal court to their roles in a more than $5 million conspiracy to provide bogus IDs to illegal immigrants via the St Joseph License Office.

Jessica M. Gonzalez, 21, of St. Joseph, pleaded guilty before U.S. District Judge Gary A. Fenner on Tuesday, Sept. 4, 2012, to the charge contained in a Jan. 10, 2012, federal indictment.

Her brother, Stephen E. Vanvacter, 25, also of St. Joseph, pleaded guilty to the same charge on Aug. 31, 2012.

By pleading guilty, Gonzalez and Vanvacter admitted they participated in a conspiracy to transport illegal aliens, to unlawfully produce identification documents, to unlawfully transfer another person’s identification and to commit Social Security fraud.

Their sisters and co-defendants, Sara M. Gonzalez, 21, and Christina Michelle Gonzalez, 24, both of St. Joseph, have pleaded guilty to the same charge.
