ST. LOUIS (AP/KMOV) -- The St. Louis County prosecutor says no charges will be filed in connection with the overdose death of the girlfriend of Anheuser-Busch heir August Busch IV.
Twenty-seven-year-old Adrienne Martin died Dec. 19 after spending the night at Busch's estate.
Prosecuting Attorney Bob McCulloch said Thursday the investigation into Martin's death is closed for now but it could be reopened if more information becomes available.
The police report states that Martin and Busch were drinking most of the night of Dec. 18, and they went to sleep around 3:30 in the morning.
Officials say Busch woke the next day around 12:45 in the afternoon and left the bedroom, and could not wake Martin when he returned around 1:00. A 911 call was made 12 minutes later.
St. Louis County Medical Examiner Mary Case said Wednesday an autopsy showed Martin died of an accidental overdose of the prescription painkiller oxycodone. McCulloch says Martin also had cocaine in her system.
The report also stated a straw with white residue was in the jacket she was wearing when she died, and a similar straw was found under the mattress.
Police say Busch’s bedroom was in disarray, and items including weapons and ammunition were scattered around. A loaded shotgun and loaded Glock pistol were reportedly found in the bathroom.
McCulloch added that there were several pill bottles and medicine bottles that had prescriptions for Martin. Two were empty, but had traces of cocaine and oxycodone.
McCulloch says Busch is no longer participating in the investigation, so they have hit a dead end, for now.
Busch was the last of a long line of family members to run Anheuser Busch before it was sold to Belgian brewer InBev in 2008.
