The cause of death was drowning, but Chief Deputy Coroner Bob Brenczewski says her blood alcohol level was 0.228 – more than twice the legal limit for driving – and there was a significant level of the anti-anxiety drug Xanax in her system too.

He said there was enough drugs and alcohol in her system to have caused her death.

The Sybaris, which bills itself as a romantic getaway with private pools and whirlpools, is at 7500 W. Lincoln Highway in Frankfort.
