MILTON, Ga. (AP) — Two months before police say a high-priced prostitute calmly left a Google executive dying from a heroin overdose on his yacht, the woman panicked on the phone with a 911 dispatcher as her boyfriend lay on the floor of their home in the throes of a fatal overdose.

Police said Thursday they are re-examining the death of Dean Riopelle, 53, the owner of a popular Atlanta music venue. Riopelle had been dating Alix Tichelman, 26, who is now charged with manslaughter in the November death of Google executive Forrest Hayes. She was never charged in Riopelle’s death.
