A little bit more information in
this article:
According to reports, Silman owed the Tax Authority and National Insurance Institute of Israel about NIS 15,000 (some $3,800), but procedural errors and lost court cases against the authorities caused the debt to expand. Silman owned a small delivery service, and could not meet the debt. Eventually he lost his apartment.
And also this:
Idit Lev of the Rabbis for Human Rights organization accompanied Silman over the past year. "The State pushed him over the edge," she said. "He did not want to harm himself. He only wanted a roof over his head. They foreclosed his home, and later seized his mother's apartment as well."
Rabbi Lev said Silman was not eligible for rent support because he had previously owned an apartment. He was living at a friend's apartment, free of charge, she said.
Why was he not eligible for rent support? Did he default on housing payments for the apartment he had owned? Lots of open questions...
