I've tried to locate any wife for Contreras. One source said he was married, but no name of supposed wife, and a search resulted in no pictures of him and a wife. When he was sworn in as a District Judge in 2012, he spoke about his deceased father-in-law. His mother, Amparo Contreras was photographed helping him put on his robe. Don't you think that that would be a wife's role? In this article, I discovered that in 1994, he was hired by then U.S. Attorney for D.C., Eric Holder. Here's the link to the whole article and pictures:
