1. There is no homeless shelter?
2. Eviction notices never come as a surprise. Even an emergency eviction has several days notice associated with it. I have had to evict tenants for things like firing a shotgun through the wall and into the adjoining apartment. Even then, no one is put on the street unexpectedly.
3. The only exception ever is a domestic restraining order, which is not an eviction. I have had co-workers where their wife would serve them with a notice to keep out with no prior notice. But that is not an eviction.
Exactly, evictions take at least two months. This guy also had his day in court.
The article at Pennlive brings out that this day was known to be coming and that police noted, once inside, that no preparations for moving had been made.
