St. Louis, MO (KSDK) - Prosecutors in St. Louis County will now decide what if any charges might be filed following the death of Adrienne Martin.
Martin, the girlfriend of August Busch IV, was found dead in his Huntleigh mansion in December.
While they're not willing to categorize the case as criminal, prosecutors call it an ongoing investigation. This comes after Martin's toxicology report was released to her family last last week. Sources say it showed lethal levels of cocaine and the painkiller oxycodone in her system.
"I'm still in shock and I don't think I will ever be able to accept or understand any of this," said Christine Trampler, Martin's mother.
Busch's attorney Art Margulis says they are not at this point, working with prosecutors. In fact, he says they have yet to receive the official toxicology results.
We spoke with Jim Martin, a former U.S. Attorney, who is not involved in the case, about how prosecutors are likely to proceed.
"First, there is no case to pursue if the autopsy does not specifically say the cause of death was drugs in the system," he said.
Martin says the next question is how the individual consumed the drugs, whether she was a willing participant. He says everyone involved will likely be interviewed.
"If you re the supplier of the drugs to someone who dies, it can expose you to criminal liability," he said. "The question, in part, will be: is it a matter worthy of criminal prosecution?"
He says this determination can often take a great deal of time and with the big names involved it will not be made lightly.
"In these high profile cases, whatever decision you make some people are always going to question you and suspect about what the motivation was," Martin said.
Prosecutors say they hope to have more to release by later this week or early next week.
