Police are investigating after a woman was found dead at the home of a former chief executive of Budweiser in St Louis, Missouri.

The body was found on Sunday afternoon at the home of August Busch IV, a scion of one of the Anheuser-Busch families which founded the brewery that produces Budweiser, Bud Light and other beers.

Police and the county medical examiner's office yesterday identified the woman as Adrienne N Martin, aged 27. An autopsy has been done but its results have yet to be made known.

However, the St Louis county forensic administrator Suzanne McCune said that there had been no signs of trauma or illness.

Art Margulis, an attorney for Busch, said that Martin was a friend of Busch who had been visiting the home. He said there was "absolutely nothing suspicious". "It was a tragic death of a young woman," he said.

STLtoday.com, the website for the St. Louis Post-Dispatch, quoted anonymous friends as saying that Martin and Busch were dating. The newspaper also said that Martin had an eight-year-old child.

A police statement said that an emergency call had been received at 1.15pm on Sunday about an "unresponsive person" at the address. Martin was dead when paramedics and officers arrived, it added.

The Post-Dispatch quoted a police source as saying that the case was being investigated as a possible overdose.

Busch, 46, was chief executive at Anheuser-Busch from 2006 until 2008 when the company was bought by InBev. The $52bn merger created the world's largest brewery, of which Busch is a member of the board of directors.
