Note the tight debris field at the beginning of the loop indicating the high rate of speed. If there are more intact, heavier remains, they will be found in LA. As the loop progresses, the lighter material sinks into the lower atmosphere (prob < 60K ft) and the upper air wind starts to spread it perpendicular to the original path. Forecast winds at 53,000 ft over Shreveport are 280 deg at 53 kts (pretty light for this time of year). The debris spread matches that expectation.
