Jacqueline Szczepanik, 43, a Brazilian‑born missionary living in Omaha, Nebraska, vanished with her husband Vanderlei and their 7‑year‑old son Christopher after being last seen between December 17 and 18, 2009. The family had been living and renovating a former school building used as a missionary training center. A friend who contacted Jacqueline daily alerted the pastor when she couldn’t reach her in early January 2010, and a missing person report was filed on January 8, 2010. Police found the family’s personal belongings intact in the home, and both vehicles—a gray Nissan pickup and a beige 1995 Dodge Caravan—were later found abandoned in Omaha.

Investigators tied the disappearances to three Brazilian men who had worked on the renovation and soon used the family’s credit and business cards at ATMs. In May 2010 Jose Carlos Oliveria‑Coutinho, Elias Lourenço‑Batista, and Valdeir Gonçalves‑Santos were arrested on fraud charges.

What can readers who knew Jacqueline, her family, or their work in Omaha add that might help fill remaining gaps about where Jacqueline and Vanderlei’s remains might be located?
