Cynthia Braga went missing seven years ago, in late June 2003, and authorities have yet to track her down.
It was reported to Montgomery County police that she was missing from her residence in Wheaton. Her family was concerned because they hadn't heard from her, and she normally spoke with her father in Brazil every day.
Braga has not been seen or heard from since June 30, 2003, when she last spoke to her father over the phone.
Braga's adult sister, who lives in the area, has not had any contact with her.
Braga's husband, Roberto, was arrested in March 2006 and charged with first-degree assault in an incident that occurred the previous fall involving his girlfriend.
Investigators said Roberto Braga had held a knife to the woman's throat because he believed she was having an affair. According to authorities, he threatened her and told her no one would ever find her body.
Roberto Braga was released on his own recognizance and the case eventually was closed.
Authorities now believe there might have been foul play involved in Cynthia Braga's disappearance.
At that time of her disappearance, Cynthia Braga was described as a 32-year-old Brazilian female, 5 feet 7 inches tall, weighing 120 pounds, with brown eyes and shoulder-length black hair.
