Ion was not the owner; he rented the sites as a venue for his art and maybe the art of others . Ng is the owner and he owns a number of sites in Oakland. I do not know who promoted the development of the interior of the building into a rabbit’s warren of rooms for sleeping, living in or doing art in. Whoever did that is culpable along with Ion and Ng.
I hope all involved in promoting such a sty/warren are hung. No sympathy for those who exploit the young and then do not mourn their deaths. Sick.
The one who holds the lease will pay for his actions.
