I didn't see this mentioned anywhere else, but, according to a Boston Globe article: http://www.boston.com/sports/baseball/minors/articles/2006/08/10/ex_peabody_star_allison_suffers_her oin_overdose/?p1=MEWell_Pos1
former high school phenom and Marlins 1st round pick Jeff Allison overdosed on heroin early this week.  He was released from the hospital a day after he was brought in.  

Anyway, sad story.  I'd guess this will probably all but close the book on a bright pitching future that might have been.
