On the evening of 23 September 1999, the Dutch widow Jaqueline Wittenberg was murdered in her house. She was found some days later. Telephone call data indicated that her personal
tax advisor Ernest Louwes had been the last one to call her on that night, but Louwes himself claimed he had been outside Deventer at the time of that telephone call. The most convincing piece of evidence was, according to the court of justice, the result of an odour test which had been performed on a knife supposedly used by Louwes to commit his crime. On the basis of this, Louwes was sentenced to twelve years in December 2000. His appeal to the
Supreme Court was rejected. In July 2003, the Dutch
Supreme Court still decided to reconsider the case because the odour test performed on the knife had proven to be incorrect. In fact, the knife in question had not been the murder weapon at all. Louwes was released until further notice.
DNA profiling was then used by the
Forensic Institute in order to examine the blouse the widow had been wearing at the time she was murdered. However, the results of this test seemed to corroborate once again that Louwes had been the murderer. So on the basis of this new evidence, Louwes was again sentenced to twelve years by the court at
Den Bosch in February 2004. Although the DNA proof in question had been admitted by the court because it was under
chain of custody, this is the first controversial part of the case. In fact, it has not become clear at all where the blouse used as crucial evidence had been during the initial period after the murder had been discovered. Two detectives who were officially involved from the beginning were questioned. One of them confirmed in writing that he did not know where the blouse had been shortly after the murder, while the other one had given up his involvement in the case almost immediately after the widow's body had been discovered. These two detectives will possibly be prosecuted because of
perjury. After spending eight years of his sentence in prison, Louwes was released in April 2009. == New investigation ==
