The man who shot dead his neighbour, her 14-year-old daughter and an Erasmus MC lecturer last week was on the verge of being evicted from his home, the AD said on Monday afternoon.

Medical student Fouad L had not paid rent for several months and had built up arrears of nearly €3,100 with housing corporation Woonbron, the AD said, based on court documents.

A month before the fatal shooting a judge in Rotterdam had said he could be evicted, but as yet it is unclear if the pending eviction was one of the drivers behind his killing spree.

More has been emerging about L, who studied medicine at Erasmus university but had been declined a degree because of doubts about his mental health. The university had asked him to undergo a psychiatric examination after being warned about him by the public prosecution department, but L failed to comply.

The university said on Friday there were signals L was targeting the exam board when he went to the teaching hospital in a bulletproof jacket, after killing two of his neighbours and attempting to set his own home on fire.

At the hospital, he shot dead lecturer and GP Jurgen Damen and also set a fire in another part of the university.

L was a member of a 4chan chat group with the slug “political prosecution of Asperger men” and talked in May about how the university had refused to give him his diploma and that he therefore lost his job and is destitute.

Officials are now trying determine if L had any contact with social workers or other bodies following his convictions for animal abuse. They are also trying to put together a timeline of the period leading up to the shooting.

Woonbron has declined to comment further on the pending eviction.
