Alix Tichelman, the alleged high-priced escort who is accused of administering a lethal dose of heroin to a former Google executive, was charged Wednesday with manslaughter, prostitution, and multiple drug counts.
Tichelman is suspected of meeting Hayes aboard his yacht, injecting him with heroin, and leaving after he passed out.
Hayes eventually died of an overdose, according to authorities.
Tichelman and Hayes reportedly met on SeekingArrangement.com.
According to her Facebook page, Tichelman is from Atlanta. She describes herself on Facebook as a stripper/exotic dancer, model, make-up artist, and hustler.
On Facebook, Tichelman posted frequently about death, drugs, guns, and the adult entertainment industry.
Hayes is survived by his wife and five children. On a memorial site, a co-worker described him as "one of the most intelligent individuals I ever had the pleasure of working with. More importantly he was also a great guy and just fun to be around."
After identifying Tichelman in the video, police arrested her by luring her to a Santa Cruz hotel with the promise that a client would pay her more than $1,000 for sex.
Tichelman is being investigated for a second heroin death, police say.
The Milton, Ga. police department said Thursday that Alix Tichelman called 911 on September 6, 2013, to report that Dean Riopelle had overdosed on heroin, the Associated Press reports.
Riopelle later died and a medical examiner concluded that he did in fact die from a heroin overdose. Investigators are now taking a second look at his death to make sure they didn't miss anything.
