The Bahamas authorities still have not concluded their investigation of the fatal crash that cost the lives of nine people.  During an autopsy of the pilot, Luis Morales III, it was discovered that he had cocaine in his urine as well as alcohol in his stomach. Authorities have not yet announced the amount of the substances that were found in his system and how they might have affected the pilot. 

It was discovered after the crash that the pilot, Morales, had pleaded no contest to cocaine possession in a Florida court just twelve days before the fatal crash. Morales was sentenced to three years probation and was supposed to have his pilot�s license revoked due to the conviction but authorities had not yet done so at the time of the crash. 
 

Whether drugs and alcohol played a key role in causing the crash is still unknown, authorities are also looking into other causes. It is believed that the airplay may have failed because the aircraft had not undergone routine maintenance and required modifications to the fuel pump and fueling system. Another suspected cause is the fact that authorities believe the aircraft was flying at 700 pounds over it�s maximum weight capacity. Authorities said that the aircraft was certified to carry only 8 passengers and Aaliyah�s plane was carrying 9 people as well as the heavy equipment needed to film a music video.
