Adrienne Martin Found Dead In the Home Owned by August Busch IV

Dec. 24, 2010 — -- Investigators are working to determine what happened to 27-year-old Adrienne Martin, who was found dead earlier this week in the St. Louis-area mansion of August Busch IV, the heir of the Anheuser-Busch dynasty.

Martin's death was reported to the police just after 1 p.m. on Dec. 19, according to the Frontenac Police Department. Her body was found in the nearly $2 million mansion in Huntleigh, Mo., owned by Busch, the former Anheuser-Busch CEO.

In a statement, Thomas Baker, Frontenac police chief, said that Martin's body was found with "no apparent signs of trauma or other indications of cause of death."

Busch, 46, is the great-great-grandson of Anheuser-Busch founder Adolphus Busch, and had been in charge of the famed brewery until 2008, when the long-time family company was sold to InBev.

It is not immediately clear whether Busch was at his home at the time of Martin's death.

Calls made to Busch's attorney, Art Marguilis, weren't immediately returned, but Marguilis told the St. Louis Post-Dispatch that there is "absolutely nothing suspicious about her passing."

"It's a tragic and untimely death of a young person," he said, "A very kind young person, by the way."

While officials at the Frontenac Police Department declined to speculate what may have caused Martin's death, an unnamed source from the squad told the Post-Dispatch that an overdose was possible.

St. Louis County forensic administrator Suzanne McCune said Thursday there were no signs of illness or trauma and that results of an autopsy could take four to six weeks, according to The Associated Press.

It has been widely reported that Martin and Busch had been dating for nearly a year.

In recent years Busch has reportedly kept out of the public eye, but a 1997 profile of him in Fortune magazine detailed his "tumultuous" history.

Known most as simply "The Fourth," Busch wore cowboy boots everyday and spoke candidly to the magazine about his role in the company, shooting down claims that his life was made any easier by his position of power, while still admitting that he was part of the family tradition that requires each Busch baby to drink a few drops of Budweiser on the very day they're born.
