Not really all that shocking.  I mean they were at a bar before the crash right?  I would assume they had a few adult beverages while they were there.

According to the documents that the Miami Herald obtained, the divers who recovered the bodies of Jose Fernandez and his friends had a strong odor of alcohol:

Miami Marlins pitcher Jose Fernandez and two of his friends who perished in a violent boat crash off of South Beach last month all had a strong odor of alcohol on them when their bodies were recovered by divers, according to a search warrant affidavit obtained by the Miami Herald.

The toxicology tests for the young men are complete but have not been released by state investigators, citing an exemption in the public records law for open criminal investigations. Nor have the autopsies been released.

Either way this sucks.  But it would be even more tragic if they were drunk and it contributed to the crash.
