The details of the murder emerged later; the accounts of the investigators and Van der Graaf were consistent. He had planned the attack using information obtained from the Internet; printouts of a map of the scene of the crime and schedules of Fortuyn's appearances were found in his car. In two boxes of cartridges found at his home, seven cartridges were missing, the exact number loaded in his gun. The attack has been described as the work of a single person, an amateur shooter who used a relatively simple plan and did not prepare a good escape route.
