The 27-year-old girlfriend of August Busch IV died in bed at his Huntleigh mansion in Missouri shortly before Christmas 2010.
Coroner Mary Case released the final report — forwarding a copy to law enforcement agencies for possible criminal charges.
The toxicology report indicates that the companion of the Anheuser-Busch heir had ingested cocaine and Oxycodone.
