Two months after an almost-completed Florida International University pedestrian bridge came crashing down, killing six people, we're still looking for answers.

Contrary to previous reports, cracks in the concrete may have signaled imminent failure. A FIGG engineer who left the Florida DOT a message two days before the collapse said he wasn't concerned about the cracks from a safety perspective, but three independent engineers who examined photos of the bridge after the collapse concurred the cracks indicated potential structural problems. They said the cracks should have prompted construction to stop for an in-depth review, which would have likely resulted in the truss connection being re-engineered and reinforced.

Government officials are also looking into a crane operator who witnesses said fled the scene during the collapse. Police don't believe he did, or that he caused the failure, but that he drove the crane a short distance away and stuck around to offer help. A lawyer from the crane company stated that the unidentified operator moved the crane out of the way so emergency vehicles could have access to rescue people under the rubble.

Investigations are still ongoing, so stay tuned for the latest reports.
