This info was in today's AIN email. I hate to say it but the cause is starting to look pretty obvious, hopefully I'm wrong:
Preliminary flight tracking data shows the aircraft crossing over the extended Runway 11 centerline at 148 knots, about 300 feet above the terrain, less than a mile from the threshold, and descending at 1,125 fpm. The data also shows the aircraft banking in an apparent attempt to recapture the heading for a short final.
