A 27-year-old woman was found dead in a Missouri home owned by August Busch IV, the former chief executive of Anheuser-Busch Cos.
Authorities in Missouri confirmed Thursday that Adrienne Nicole Martin was pronounced dead at 1:26 p.m. Sunday at the home in Huntleigh, Mo., an affluent St. Louis suburb.
Paramedics responding to a 911 call found no apparent signs of trauma or other indications of a cause of death, according to a report released by the Frontenac, Mo., Police Department, which is investigating the incident in cooperation with the St. Louis County Medical Examiner.
It could take four to six weeks for tests to be completed to determine the cause of death, said Suzanne McCune, forensic administrator for the county medical examiner's office.
Thomas M. Becker, chief of police for Frontenac, said he couldn't comment on the investigation until his office receives the medical examiner's report.
Mr. Busch didn't respond to emails seeking comment Thursday. Art Margulis, a lawyer for Mr. Busch, said "there's absolutely nothing to indicate that the death was caused by any suspicious circumstances." Mr. Margulis described it as "a tragic death of a young person, a very nice person."
Ms. Martin's family couldn't be reached.
Mr. Margulis said Mr. Busch, 46 years old, was at the residence at the time of the 911 call and described Ms. Martin as a friend of the former beer executive. He said there were multiple people there at the time and he isn't sure who made the 911 call.
Mr. Busch, who was divorced in 2009, had been seeing Ms. Martin regularly for about a year, according to a person familiar with the matter. He is a director at Anheuser-Busch InBev, which was created by InBev NV's $52 billion acquisition of Anheuser-Busch Cos. in 2008.
Ms. Martin also was divorced and had an 8-year-old son, according to friends. A friend of Ms. Martin said she was a part-time model who had worked at several local fashion shows, and had been pursuing a master's degree in art therapy at Southern Illinois University Edwardsville.
She also had worked as an office manager for a cleaning company. Her death was reported Thursday on the St. Louis Post-Dispatch's website.
A spokeswoman for Anheuser-Busch InBev, which is based in Leuven, Belgium, declined to comment. The company is the largest brewer in the world by sales.
Mr. Busch became CEO of Anheuser-Busch in 2006, the sixth member of the Busch family to run the Budweiser maker.
In the 1980s, Mr. Busch allegedly wrecked a sports car; a female companion was killed in the accident, and he left the scene. Police didn't press charges. In 1985, Mr. Busch was arrested after allegedly leading police on a high-speed car chase in his Mercedes and being accused by police of trying to run over two officers. A St. Louis jury acquitted him of assault charges.
Mr. Busch declined to comment on both incidents for a 2008 Wall Street Journal profile.—Ilan Brat and Douglas Belkin contributed to this article.
