Karst Tates, the man who smashed his car into a monument in Apeldoorn after killing seven bystanders on Queen's Day, did not have any plans for his life after 30 April.

Karst T. had been fired and had cancelled the rent for his apartment as of May 1. He did not have a prospective new home. Police searches of his house revealed that he had not removed any of his belongings yet. According to the national police various sources confirmed this.

One-man operation
The Public Prosecutor’s Office assumes Karst Tates acted alone and fears his actions will never totally be explained. No weapon was found in Mr Tates’ Suzuki Swift, just a flag and binoculars.
The 38-year-old Karst Tates who genuinely targeted the Dutch royal family on Queen's day smashed his car through crowds and crush barriers and rammed a monument right when the royal family was passing by in an open-top bus. He died from his injuries the following night.
 

Statements by Karst Tates
On the day of the attack the Public Prosecutor’s Office stated it assumed that it was an attack on the royal family. The conclusion was based on Karst Tates’ last words.

Sources from the report say those statements remain the only proof of his motives in the case. The investigation of Mr Tates’ motives by the Dutch state police involving 200 detectives, did not yield any new evidence. No farewell letter was found and he had no computer. In the last years of his life Karst Tates barely had any social contacts.

Behaviour analysis
The state police’s investigation was terminated three weeks ago. Its conclusions are expected to be disclosed in the beginning of September. First, a post mortem behaviour analysis will be made of him by the NIFP, the Dutch national psychiatric legal investigation centre.

The investigation attempted to rule out all possible scenarios. The police made elaborate inquiries after an inhabitant of Delfzijl, in the north of the Netherlands, claimed she had seen a black Suzuki during the Queen’s visit to the Eemshaven, a nearby port.

Karst Tates' radical rightwing ideas and possible underlying meanings of his tattoos were also investigated.

Investigation results
A spokesperson says the Public Prosecutor’s Office does not want to comment on the case until September, when the results of the investigation will have been presented. In the first hours after the incident it was held possible that Karst Tates had accomplices. Bystanders claimed they had seen a passenger being swung out of the car.

Researchers from the National Forensic Institute were given access to the victims' bodies immediately to find evidence. This resulted in hectic circumstances in hospitals, where relatives had to wait for hours until the bodies were released.
