On November 2, 2004, Mohammed Bouyeri murdered Theo van Gogh, an Amsterdam filmmaker and columnist. Police arrested him in the city shortly afterward, and at his trial he admitted the killing. Eight and a half months later the Amsterdam District Court convicted him of murder committed with terrorist intent, of the attempted murder of police officers and bystanders, of threatening and impeding the work of a member of the Dutch parliament with terrorist aims, and of an offense under the arms law. It sentenced him to life imprisonment, which in the Netherlands means detention for life unless the Crown grants a pardon.
The case did not end with the sentence. Bouyeri stood in the dock again from December 2005 as one of fourteen defendants in the trial of the Hofstad group, a network of young Islamist radicals whose existence the Dutch General Intelligence and Security Service, the AIVD, had tracked since 2002. That trial and its appeals ran until the end of 2010. Parliament, the intelligence oversight commission and the Council of State spent years more on whether the service had underestimated him and whether anyone else had known what he planned. He was 26 at the time of the killing. As of November 2024 he was still serving his sentence.
Bouyeri was born in Amsterdam to Moroccan parents and held both Dutch and Moroccan nationality. He was raised and educated in the Netherlands.
Before 2004 he was known to the police and the Public Prosecution Service in Amsterdam, though not for anything resembling what he went on to do. He had convictions for resisting an officer, for insult and for simple assault. Two further cases were open in the autumn of 2004, both for resisting arrest and for threatening behavior. On September 29, 2004, five weeks before the killing, he was fined for riding public transport without a ticket in Amsterdam, made a disturbance and was arrested.
The AIVD first noticed him in August 2002, and only at the edge of something else. The service was investigating a group of orthodox Muslims in Amsterdam, later called the Hofstad network, and his registered address turned up in information about one of its members. That same month a piece he had written on norms and values, built around passages from the Koran, appeared in a neighborhood publication.
Over the next two years his address became one of the places where the network met. Police reported gatherings there in December 2002, and by the spring of 2003 it was a regular meeting point. In mid-2004 the Syrian man whom the AIVD regarded as the network's spiritual leader often stayed there; the Syrian used several people in the same way, and Bouyeri was one of them. The government's account describes his role in this period as supporting rather than central. He provided an address and a car to the network's core members, he was not one of those core members, and he had no part in the network's travel to Pakistan.
The police saw a change in him. In the autumn of 2003 Amsterdam police reported outward signs of growing radicalization, and on October 8, 2003 they told the AIVD so directly. That October other members of the network were arrested in Amsterdam, The Hague and Schiedam. In April 2004 an AIVD source described him as susceptible to radical interpretations of Islam, and at the service's request the police checked their records and sent a photograph. In June 2004 further arrests connected to the network were made in Portugal during the European football championship. In July 2004 he was described as standing on the periphery of the group around one of its leading figures. On September 30, 2004 the Amsterdam-Amstelland police informed the regional intelligence service that he had grown more fundamentalist over the preceding years.
None of this, the government told parliament, showed that he was a key figure in the network or that he was preparing an act of violence. The police and the AIVD had found no concrete evidence that he was involved in the attack preparations they suspected in October 2003 and June 2004, or in any other specific offense. He was not placed in the CT Infobox, the joint register of people of counterterrorism interest. The ministers concluded in November 2004 that, in hindsight, the services could not reasonably have reached a different judgment.
The oversight commission for the intelligence services, the CTIVD, reached a more critical view in 2008. Its report found that the AIVD could and should have known before the killing that Bouyeri used the alias Abu Zubair and that he was the translator and author of two texts that glorified violence. It found that the service had underestimated his active and important role and his violent character, and had given him too little attention. It also found that the AIVD had had no information before November 2, 2004 pointing to a concrete threat from him or any other member of the group against the victim or anyone else, no information pointing to his involvement in preparing attacks, and none showing him as a leader, mentor or driving force of the group. A better file on him, the commission concluded, would still not have shown a person seriously suspected of direct involvement in attack preparations, and the decision not to place him under the closest surveillance had been reasonable. The Minister of the Interior accepted every finding except the first, on the alias and the two texts, and argued that recognizing them would not have revealed a concrete threat.
The murder took place in Amsterdam on Tuesday, November 2, 2004. Police arrested Bouyeri in the city shortly afterward. The attempted murder of police officers and bystanders of which he was later convicted belongs to the same events.
That day police arrested eight other people. Four were held in custody; the investigating judge released two and the public prosecutor released two. On November 5 a 23-year-old man of Moroccan origin was arrested; he was brought before the investigating judge on November 8 and held. He was the ninth man arrested since the killing, counting Bouyeri.
On November 5 the investigating judge ordered Bouyeri held in pre-trial detention. The same day the chief prosecutor in Amsterdam announced the grounds on which he was held: the killing and participation in a criminal organization with terrorist characteristics. Dutch practice gave him to the public as Mohammed B.
On November 10, 2004, police in The Hague arrested further members of the network; two of them, Jason W. and Ismaël A., were later convicted of attempting to murder officers of the arrest team. The same day the Minister of Justice and the Minister of the Interior sent parliament a long letter with a reconstruction of what the police and the AIVD had known about Bouyeri and the network. They announced a program of measures: wider observation of people linked to terrorism or radicalization and more capacity and data access for the AIVD, more protection capacity for the royal and diplomatic security service, a means to have websites with radical content taken down, programs to counter radical currents in Islam and to train imams in the Netherlands, tighter rules on entry and residence for people who spread radical ideology, plans to limit dual nationality and to allow nationality to be revoked from dual nationals who seriously harmed the state, and a review of offenses such as insult, blasphemy and the glorification of serious crimes. The letter recorded that threats against politicians and other public figures were coming more often and growing more serious.
The criminal case against Bouyeri for the events of November 2 was tried separately from the case against the wider network. It came before a three-judge panel of the Amsterdam District Court, sitting in a high-security courtroom in Amsterdam, in a two-day hearing in July 2005.
He presented no defense and waived his right to one. On July 12 he admitted the killing in court and asked for the maximum sentence. The public prosecutor asked for life imprisonment. The prosecution also asked the court to strip him of the right to vote and to stand for election.
The court delivered its judgment on Tuesday, July 26, 2005. It convicted Bouyeri of the murder and found that the murder had been committed with terrorist intent: that he had deliberately set out to spread fear among the Dutch population and to disrupt the way people in the country lived together. It convicted him of the attempted murder of police officers and bystanders, of threatening Ayaan Hirsi Ali with a terrorist act and of impeding her work as a member of parliament, both with terrorist aims, and of an offense under the arms law.
The court imposed life imprisonment, the most severe penalty in Dutch law, and followed the prosecution's demand in full on the sentence. It rejected the request to deprive him of his electoral rights, reasoning that he so clearly rejected democracy that he was unlikely ever to use them. He was to serve his sentence apart from other prisoners, so that he could not spread his ideas among them. He heard the verdict without visible reaction, shook hands with his lawyer and was led out.
Both sides had two weeks to appeal. He began serving the life sentence.
When the Amsterdam verdict came down, prosecutors described Bouyeri as a leading figure in the Hofstad group but had not charged him with membership in the Amsterdam case. The national prosecutor's office was to decide whether to pursue that separately, and it did. On December 5, 2005 the trial of fourteen defendants in the Hofstad case opened, and Bouyeri was one of them. It was heard by the Rotterdam District Court.
The court gave its judgment on March 10, 2006. It held that the Hofstad group was a terrorist organization, and it convicted nine of the fourteen defendants of participation in a criminal organization and of participation in a terrorist organization; five were acquitted. It found that the group's aim was to incite hatred of, and to threaten, people who were not Muslims, conduct the judges said laid the ground for crimes that struck at the core of the democratic order. Jason W. and Ismaël A. received the heaviest sentences, fifteen and thirteen years, for the attempted murder of police officers in The Hague on November 10, 2004. The court found Bouyeri to be a leader of the group. Because he was already serving life, he could not be punished further, and no additional sentence was imposed on him.
On April 3, 2006 the Minister of Foreign Affairs, with the Minister of Finance, issued the Terrorism Sanctions Regulation 2006, which froze the assets of the Hofstad group and of the persons named in its annex and barred anyone from providing them with funds or financial services. Bouyeri's name appears in the annex, spelled Mohamed Bouyeri.
The Hofstad case did not settle for another four years, though none of what followed changed Bouyeri's position. In 2008 the Court of Appeal in The Hague acquitted seven appellants of participation in a terrorist organization. It also acquitted them of inciting hatred, on the reasoning that the offense applied only when directed at a vulnerable minority, and it reduced the sentence of Ismaël A. to fifteen months.
On February 2, 2010 the Supreme Court of the Netherlands set that judgment aside. It held that the appeal court's definitions of the existence and structure of a criminal or terrorist organization were too strict, and that its reading of the offense of inciting hatred had no foundation in law. The seven cases were sent back for retrial, which was heard by the Amsterdam Court of Appeal.
On December 17, 2010 the Amsterdam Court of Appeal held that the Hofstad group had been an organization whose aim included the commission of terrorist offenses. Its sentences ranged from fifteen months to thirteen years. Jason W. received the highest, with the court taking into account that he had been 19 at the time; most of the others had already served their sentences in pre-trial detention. The court described the group as young men gathered around Mohammed B., who had met at the place where he lived, discussed violent jihad there and exchanged documents.
Whether Bouyeri acted alone was asked repeatedly after 2005. In a television broadcast in 2014, the prosecutor who had led the investigation said he believed Bouyeri must have had accomplices. On October 17, 2014 the Minister of the Interior asked the CTIVD to examine three questions: whether the AIVD had destroyed microphone recordings made in a building in The Hague used by the group, what the service had learned from November 2, 2004 onward about possible accomplices, and whether it had wrongly kept such information from the Public Prosecution Service.
The commission reported in December 2015. The recordings had not been destroyed; the service still held them, and in 2015 it listened to all of them, helped by technology that made the 2004 recordings easier to understand. The commission found no concrete indications that anyone had known of or taken part in the preparation of the murder, and no concrete indications from any other information that Bouyeri had accomplices. It found communication between the AIVD and the prosecution service lacking at several points. Between 2004 and 2011 the service had received hearsay about four people who might have known of his plans beforehand. It had sent official reports to the prosecution service about three of them shortly after the killing, but could not establish the identity of the fourth with certainty. In the commission's view the AIVD should have consulted the national counterterrorism prosecutor on each of those occasions, and for ten of them it could not tell whether that had happened, because no record of it existed. The Minister of the Interior adopted the commission's recommendation that such consultations take place and be put in writing, and instructed the service to share the relevant information with the counterterrorism prosecutor.
In 2019 the question reached the Council of State, the highest administrative court. A journalist investigating the killing had asked for access to the records of tapped conversations about the murder and the Hofstad group. The Minister of the Interior refused on grounds of national security. On August 28, 2019 the Council of State, which had been allowed to inspect the AIVD's documents, found the minister's explanation not sufficiently substantiated. It accepted that some secret documents could threaten national security if published, but it was not convinced that the service had handed over every report of tapped conversations and said there might be more from before the murder. It ordered the minister to reconsider the request and to look again for further reports, and to explain if any had existed but were gone.
Bouyeri was first held in the most restrictive regime in the Dutch penal system. A dispute with another detainee there in May 2011 led to a complaint against him for attempted manslaughter. In 2012 the Public Prosecution Service decided not to prosecute, and by April 2013 the Court of Appeal in 's-Hertogenbosch rejected the other detainee's request to order a prosecution, finding it undesirable.
In August 2016 he was moved from that unit to a terrorist ward in the same complex.
As of November 2024, twenty years after the killing, he was serving his life sentence in the Netherlands.
When Bouyeri was sentenced in 2005, a Dutch life sentence carried no parole. The only way out was a royal pardon, which was almost never granted; only two of sixteen earlier life prisoners had been pardoned early. In 2013 the European Court of Human Rights ruled that a life sentence with no prospect of release was inhuman, and in 2015 a judge in Assen cited that lack of hope in a ruling. In April 2016 Bouyeri was one of 40 people serving life in the Netherlands, and the governing parties were pressing for a review of life sentences after 25 years.
The procedure that followed works in two stages. After 25 years of detention, the Advisory Board on Life Prisoners advises on whether reintegration activities can begin. If they can, the Minister decides on a pardon two years later, roughly 27 years into the sentence. In 2022 the Council for the Administration of Criminal Justice and Youth Protection advised that the pardon procedure be replaced by a judicial review, which would require a change in the law. Bouyeri's detention began in November 2004.
His standing in the Hofstad group was judged differently over time. The government's account of November 2004 described a supporting figure who provided an address and a car, not a core member. The CTIVD found in 2008 that before the killing the AIVD had no information marking him as a leader or driving force, while also finding that the service had underestimated his active and important role. Prosecutors called him a leading figure in July 2005, the Rotterdam District Court found him a leader of the group in March 2006, and the Amsterdam Court of Appeal in 2010 described the group as gathered around him. Because he was already serving life, no further sentence followed from the Hofstad finding.
The claim that he had accomplices in the killing, made publicly in 2014 by the prosecutor who led the investigation, has not been borne out by any court. The CTIVD found no concrete indications of accomplices in 2015. The 2019 Council of State ruling on the tapped conversations left open whether further reports from before the murder existed. No one other than Bouyeri has been convicted of the murder.
