The government’s psychological assessment clinic Pieter Baan Centrum has started a behavioural analysis of Karst Tates, the man who drove his car into the crowd watching the royal motorcade on Queen’s Day, killing himself and seven others.

The Telegraaf reports it is the first time the centre has carried out psychological testing of someone who is dead.
The aim of the research is to find out if Tates was responsible for this own actions, the Telegraaf said.
The inquiry will focus on his parents, friends, family members and work colleagues. In particular, the study will focus on how Tates reacted to major events in his life and on his employment history.
The motive for Tate’s attack on April 30th is still unclear. He told police officers minutes after driving his car through the crowd and into railings that it was a deliberate act.
