Louis Hagemann

Louis Hagemann (born 1953), better known as "Long Louis", is a Dutch Hells Angel convicted of several murders.

Hagemann joined the Hells Angels Amsterdam chapter and was involved in a number of criminal activities such as selling drugs, armed robberies and extortion.

Hagemann was known as one of the more violent Dutch Hells Angels.

The Canadian journalists Julian Sher and William Marsden noted that Hagemann "...had more than a hundred convictions for aggravated rape, drugs, armed robbery, assault, torture and tossing a hand grenade at a police officer".

Hagemann was described as tall, muscular man who wore his long hair in a ponytail with a red bandana always tired around his forehead.

In 1983, he befriended an young couple from Belfast, Stephen Hampton and Joanne "Jo" Wilson, who had settled in Amsterdam to escape "the Troubles" of Northern Ireland.

Hampton worked in a bar where Hagemann was a regular patron while Wilson worked as a hotel maid.

Hampton called Hagemann "very friendly" and through him he came to know Wilson.

Like many other woman, Wilson found herself unable to resist the "bad boy" sex appeal of a gangster, and was involved in a secret affair with Hagemann.

Wilson was described as being "fascinated" with the Hells Angels.

In March 1984, someone had broken into an Amsterdam apartment to stab to death Corina Bolhaar and two of her young children.

Bolhaar was an airline stewardess with KLM, the Dutch national airline.

It is believed that she was smuggling drugs for the Hells Angels.

On 20 September 1985, Wilson vanished.

Hampton worked until 4 am as a bartender and came home to his apartment where Wilson made him breakfast.

She told she would be leaving for most of the day, but would be home for dinner.

That was the last time that Hampton ever saw Wilson.

Wilson spoke with a friend at the Central Station later that day and said she was going to meet someone.

That was the last known sighting of Wilson.

Hampton was surprised when Wilson failed to show up for dinner as she had promised.

The next day, he started phoning all of her friends to ask if they had seen her, but no-one had.

Hampton went to the police, whom dismissed the meeting as a mere lover's quarrel, but did allow Hampton to file a missing person report.

Hampton who became increasing frantic as apparent that Wilson was gone launched his own search for her.

Hampton, who was unaware at the time of Wilson's affair with Hagemann, was joined by him, but the duo found no clues.

The torso of Wilson's dismembered corpse were found floating in a plastic bag in the Amsterdam-Rijn canal six weeks later by a sluice-gate operator.

The torso had been stabbed several times.

Her entire body was never recovered as Wilson's head, arms, and one of her legs were never found.

Her left leg was later found in the same canal, likewise wrapped in a plastic bag.

Hagemann was the prime suspect in Wilson's disappearance as he was a violent criminal, the torso was found floating only 300 yards from his apartment, and just before she vanished Wilson had mentioned to a friend she was going to see her "special friend Louis".

The Amsterdam police regarded Wilson's murder as a minor concern and "callously" named the investigation of her disappearance "Operation Annoyance".

The police refused to treat the Wilson case as a murder as they insisted that there was no evidence that the torso found floating in the canal was Wilson's even though the pubic hair found on the torso matched that of Wilson's pubic hair in photographs of her in the nude and the left leg was wearing one of her sandals.

Ann Donaghy, the mother of Wilson, remained convinced that Hagemann had killed her daughter, and doggedly pursued the case for decades.

Donaghy's request that what was left of her daughter be returned to County Armagh to be buried was refused by the Amsterdam police who stated that there was no evidence that the torso and leg was all that was left of Wilson.

The Wilson case became well known in the United Kingdom and Ireland.

Donaghy told Sher and Marsden in an interview that the Amsterdam police made her life a "complete hell" as the police seemed to have no interest in Operation Annoyance as they labelled Wilson's disappearance.

In 1998, Hagemann was convicted of raping his ex-girlfriend, Renetta van der Meer.

In 2001, the Dutch journalist Peter R. de Vries covered on his television show Peter R. de Vries, misdaadverslaggever (Peter R. de Vries: Crime Reporter) the massacre of the Bolhaar family in their apartment in March 1984.

The Netherlands is one of the few countries in the world to have a statue of limitations on murder, which stands at 18 years after the offense is committed.

Sher and Marsden wrote "it's not good law, but as the clock ticks it can make great TV".

Knowing the statue of limitations on the Bolhaar case would expire in March 2002, de Vries decided to look into the case, and discovered that Hagemann was the prime suspect in the murders, but that the detectives had not pursued him.
