Extremely sad.

Two things of note: her last badge-in was on a Friday, and her body was noticed on a Tuesday, so two of those days were when the office was closed. The other is that almost everybody in the office, according to the article, works remotely. So, it's possible not many people even had a chance to notice her between when she died on Friday (presumably) and when she was finally found on Tuesday.

However, that office supposedly has round the clock security, and the security on duty didn't pick up on anything unusual. Unless there's some rule against security monitoring the area where she worked, it's possible BOA corporate needs to review its physical security procedures, and possibly its security staff. In any case, something is broken there.
