MILTON, Ga. (AP) — Twice last year, Alix Tichelman found herself alone with a man suffering from a drug overdose. The first time she called 911. The second time, police say, she just walked away.

The 26-year-old Tichelman faces manslaughter charges in California after police say the alleged high-priced prostitute calmly collected her things and left as Google executive Forrest Hayes lay dying on his yacht in November following a heroin overdose.

About two months earlier in Georgia, she made a panicked call to 911 as her boyfriend Dean Riopelle suffered an overdose in their home. Riopell was the owner of a popular Atlanta music venue, the Masquerade.

Tichelman was never charged in Riopelle's death, but police said Thursday they're going to re-examine that case after the latest death in California.
