A married Google executive met the high-end prostitute who injected him with a lethal dose of heroin on dating site SeekingArrangement.
Father-of-five Forrest Timothy Hayes, 51, died on his 50ft yacht, Escape, after Alix Tichelman, 26, injected him with heroin.
Surveillance showed that rather than calling 911, she stepped over his unconscious body, gathered her belongings, finished her wine and left.
On November 23, 2013, Hayes’ body was found on his yacht in the Santa Cruz Small Craft Harbor by the boat’s captain.
Santa Cruz authorities said the two met on SeekingArrangement, a controversial sugar daddy dating site that seeks to create “mutually beneficial relationships” between rich men and financially-wanting young women.
The site was created by Brandon Wade, who also owns Carrot Dating and What’s Your Price.
Santa Cruz Deputy Police Chief, Steve Clark, said: “Ms. Tichelman works as a high-priced outcall prostitute and meets her clients through a website Seeking Arrangements.
“During interviews, Ms. Tichelman boasted of over 200 client relationships.”
Clark said her clients included other Silicon Valley executives.
Police caught Tichelman, who came froma middle-class background and studied journalism at Georgia, on 4th July after a nine-month investigation.
Officers lured her back to Santa Cruz by posing as a wealthy client offering to pay her $1,000 for sex.
Tichelman is being charged with manslaughter, possession of drugs, prostitution and destroying evidence.
Investigators believe she intentionally chose a lethal amount of heroin, but may be unable to prove intent in court.
Detectives said they are investigating Tichelman for a similar death in a nearby state.
Hayes had worked for Sun Microsystems and Apple, before joining Google as an engineer – working on their X division, which is responsible for experimental projects like Google Glass and driverless cars.
Earlier in the year, SeekingArrangements was sued in France by the Equipe d’Action group who accuse it of running a “disguised prostitution” racket, and want it to be part of the debate when French parliament discuss a landmark prostitution bill.
