Disappearance of Ophélie Bretnacher
Ophélie Bretnacher, disappeared in Budapest, Hungary on December 4, 2008. She was part of the European exchange program known as the Erasmus Programme City security cameras tracked part of her route after leaving a night club. Her bag and cell phone were later found on the Széchenyi Chain Bridge (Széchenyi Lanchid).
Political and diplomatic consequences
In the French Government, Catherine Vautrin, the Vice-Président of the National Assembly asked for a French intervention Following this intervention, French investigators were sent for the second time to Hungary. Ophélie appears on Nicolas Sarkozy's blog.
The criminal case
Her body was discovered in Csepel, in February 2009, in a backwater of the Danube. She probably drowned. The police said that death was probably the result of a suicide or accident. However, homicide cannot be ruled out because of the finding of an hematoma on Ophelie's body as well as many gray areas during the search.
One year later her friends were successful in raising 60,000 people using social media.
Improbabilities that persist in 2014
Two years after her disappearance, on December 4, 2010, Maitre William Bourdon said that the investigation continues. The article also notes:
- Some evidences (such as the walker who heard screams of women at the time of the disappearance was close to where her bag was found) have not been investigated further.
- The body of Ophélie was located in a place against the current, and it is not possible that came from the Chain Bridge.
