@Jon, we shall see. They brought out bulldozers and levelled the building after running cadaver dogs through it. I think a lawsuit is about to be filed, since the neighbors have been contacting the property owner for over 3 years about the lack of safety and security of the property, which ultimately led to this. I don't know what damage the bulldozers would do. I guess one good thing is that the roots were under the asphalt, so maybe it will survive. Or maybe the heat transfer of asphalt melting will kill them? I'll check back in spring, I guess.
@noss, evidence of arson. They ran cadaver dogs through and I don't believe they found anything. Everything points to arson, and I think it's being investigated as such. The neighbors care enough to pursue and we have a good line through to the authorities, with lots of City Hall members living nearby that have tried to work with the property owners, and the city just forked out a hunk of money on this little incident, so ... hopefully the level of care is there. I agree with you on destroying vs. good works. Kids these days ...
