Boston (WBZ)---After sifting through hundreds of Department of Transportation internal emails that were exchanged after a massive lighting fixture crashed down on the center lane of the tunnel back in February, the I-team discovered top state officials were warned of the problem even earlier than their own investigation revealed.
Austin (KEYE)---Texas requires hospitals to report their medical errors, but patients have yet to see the results. KEYE-TV investigated what's causing the hold-up and how patients can help prevent future mistakes.
Denver (KCNC)---Denver's police monitor has released an analysis concluding that Denver police officers have been routinely looking the other way for years, not arresting fellow officers when they catch each other driving drunk.
