LAFAYETTE, La. (KLFY)- Fifteenth Judicial District Attorney Keith Stutes said the investigation into the murder of a Lafayette woman will continue, despite her alleged killer’s apparent suicide inside a Brazilian jail.

Sean Grebinger was found dead in his cell in Pouso Alegre Prison Friday morning. Brazilian media reports he left suicide notes for his family.

The 48-year-old Lafayette man had been living in Brazil since his wife, Crystal Grebinger, disappeared seven years ago.

Earlier this week, he was located and arrested by Brazilian federal authorities and faced extradition back to Lafayette Parish.

Crystal Grebinger’s body has never been found, but Brazilian authorities said they found enough evidence to charge her estranged husband for murder.

Court records how she had filed for divorce and was staying at women’s shelter Faith House shortly before she vanished. Authorities said Sean Grebinger had been living in Brazil since her disappearance.

On Friday, Stutes said the investigation into the woman’s February, 2013, disappearance continues.

“The investigation into the disappearance of Crystal Grebinger began on or about February 18, 2013, and continues to be an active, ongoing criminal investigation, involving several law enforcement agencies, as certain aspects of the investigation are not complete,” Stutes said in a statement.

“In order not to compromise the completion of this continuing, ongoing criminal investigation, the District Attorney’s Office and the investigating agencies involved cannot provide further information and comment at this time.”
