Busch girlfriend died with cocaine, oxycodone in system, sources say:
"Martin was found dead Dec. 19 in a darkened bedroom at Busch's mansion in Huntleigh. There were no signs of trauma to her body, officials said.
Michael Jung, a Busch household employee, called 911 at 1:12 p.m. and said an unresponsive woman wouldn't wake up. He said he wasn't sure if she was alive because it was 'dark back there' and he was going to get a light to check.
Emergency responders pronounced Martin dead at 1:26 p.m.
In response to a question about whether drugs were found at the scene, police said in December that they found nothing to suggest a cause of death. They also said the room was dark 'due to curtains drawn in the bedroom' and that the room was outfitted with blackout curtains to block the sun."
