August Busch IV
St. Louis County, MO (KSDK) - St. Louis County prosecutor Bob McCulloch said cocaine and oxycodone were found in Adrienne Martin's system as a result of an accidental overdose and no charges will be filed in the death of the girlfriend of August Busch, IV.
St. Louis County Chief Medical Examiner Mary Case announced on Wednesday that Martin's death at Busch's home was caused by oxycodone intoxication.

McCulloch said Martin ingested oxycodone five to six hours prior to her death based on the levels of drugs in her system. He believes the cocaine was ingested about an hour prior to her death.
The 27-year-old woman was found dead on the morning of December 19 at Busch's sprawling estate in Huntleigh after spending the night at his home.

McCulloch said Busch awoke at 11:45 a.m. and went to the kitchen to make a breakfast shake. An employee at the home said Busch found Martin unresponsive in bed at 12:30 p.m. Busch and the employee were unable to wake Martin up. Police were called at 1:12 p.m. and were at the scene a minute later. Paramedics followed soon after. Martin was pronounced dead at the scene at 1:26 p.m.
McCulloch said there was no gap in the timeline.
Busch gave an initial statement to investigators after Martin's death, but has not cooperated since, according to McCulloch. Busch's employee cooperated during the investigation.
Investigators said pill bottles were found around Martin's body at the scene. One had a trace of oxycodone in it and another had a trace of cocaine in it.
McCulloch said neither Busch nor Martin had a prescription for oxycodone.
Investigators tried to determine where the drugs came from, but McCulloch said they had reached a dead end.
McCulloch said no prescribed medications were found in Martin's body. He also said there was no credible evidence of she had a heart condition, but it couldn't be conclusively disproven. He said, if Martin had a heart condition, it did not contribute to her death.
Busch's lawyer, Art Margulis, said his client was shocked by the medical examiner's findings. The lawyer also said did not have a prescription for oxycodone.
