Sylviane Finck Lozada, 51, a Belgian-born French and Spanish teacher at Brusly High School, stopped calling her family in Belgium after July 5, 2011. Her family reported her missing on July 18, 2011, after days went by with no word. Colleagues described her as sweet, intelligent, and devoted to her young daughter.

Investigators with the East Baton Rouge Parish Sheriff’s Office found a troubling timeline. Records show domestic disputes between Sylviane and her husband, Oscar Lozada, in the months before she vanished; deputies were called twice in December 2010, and Sylviane sought hospital treatment for an injury she said resulted from being pushed. Authorities say Oscar bought multiple five-gallon buckets and bags of concrete mix the day after Sylviane was last heard from. Blood was reported in the family’s garage, and four days after her last contact Oscar and the couple’s daughter flew to Venezuela and did not return as scheduled.

Sylviane’s body has not been recovered. If anyone knew Sylviane, her routines, or saw activity around Springlake Drive in July 2011, please share what can help bring closure.
