HUNTLEIGH, Mo. - Authorities were investigating the death of a 27-year-old woman whose body was found earlier this week at the suburban St. Louis home of former Anheuser-Busch CEO August Busch IV.

Police and the St. Louis County medical examiner's office yesterday identified the victim as Adrienne N. Martin of St. Charles. An autopsy has been conducted but results could take four to six weeks.

Police were called Sunday afternoon to the home in the St. Louis suburb of Huntleigh and found Martin's body.

Art Margulis, an attorney for Busch, said Martin was a friend of Busch who was visiting the home. He said there was "absolutely nothing suspicious" about Martin's death.

The St. Louis Post-Dispatch quoted an unnamed law enforcement source as saying the case was being investigated as a possible overdose.

Busch, 46, was chief executive at Anheuser-Busch from 2006 until the maker of Budweiser, Bud Light and other beers was purchased by InBev in 2008. The $52 billion merger created the world's largest brewery. Busch remains a member of the board of directors for InBev.

The Post-Dispatch reported that Busch and his wife of 2 1/2 years divorced in 2009.
