(St. Louis County) KSDK-- NewsChannel 5 has learned that both cocaine and oxycodone were found in the bloodstream of Adrienne Martin the day she was discovered dead in the home of August Busch IV.
Sources say results of the 27-year-old woman's autopsy will reveal that it was lethal levels of these drugs that caused her death.
Martin was the girlfriend of former Anheuser-Busch CEO August Busch IV. She was found dead at his estate in the Village of Huntleigh on Dec. 19.
Busch said he awoke around 11 a.m. that day and tried to awaken Martin, but couldn't.
According to Martin's mother, Christine Trampler, Busch checked on her daughter at 12:30 p.m., but assumed she was sleeping.
She was not. A call to 911 came just after 1 pm.
Frontenac Police say that call was made by Michael Jung, a member of Busch's household staff. The time of the call was 1:12 p.m.
Jung: "This girl is not waking up."
911 Operator: "Is she breathing? We don't know. It's dark. I'm going to get a light to see."
Paramedics and police officers responded and found Martin dead at the home.
An initial investigation found no signs of trauma to Martin's body, or any other indications of cause of death.
Responding to an e-mail Sunday, Trampler told Newschannel Five, "I have nothing to say about Adrienne's death. I'm still in shock and I don't think I will ever be able to accept or understand any of this."
When reached by telephone, an attorney representing Busch IV, Art Margulis, told Newschannel Five he hasn't seen the final autopsy report, and is waiting to receive that information.
Trampler says her daughter was a devoted mother to an 8-year old son Blake, had been pursuing a masters degree in art therapy, and had just started a new job with an alternative energy company.
