Hmmmmm

We're going to guess "suspicious in origin" isn't a stretch here:

• The mall was shut down in 2005 after city inspectors found 112 building, health and safety code violations there. It re-opened last November with most of those violations addressed, area activists said.
  
  "I've spent a lot of money on these buildings over the past two years," said Park, while surveying the damage Saturday.
  
  "I must have spent $500,000 on this building alone," he said, pointing to the collapsed roof near the mall's rear entrance.

In what is arguably the hottest real estate section of the city. That might not be saying much in the current housing market, but these things run in cycles.
