A high-end California call girl is facing charges of manslaughter for supplying drugs that killed a Google executive last November.

Alix Catherine Tichelman, who is described as a "high-priced outcall prostitute," supplied the heroin that caused her client, 51-year-old Forrest Timothy Hayes, to fall unconscious and die on his yacht in the Santa Cruz harbor, police told USA Today.  

The escort was charged on Wednesday in Santa Cruz County Superior Court with prostitution, transporting drugs and destroying evidence in addition to manslaughter. Police also suspect Tichelman, 26, is connected to another drug-related death in a different state.

Tichelman first met Hayes, who worked for Google's X division, on the website SeekingArrangement.com, which says it's for "for sugar daddies and sugar babies seeking mutually beneficial relationships and arrangements."

On November 23, the two were on Hayes' yacht when he allegedly took heroin, suffered "medical complications" and went unconscious, police told USA Today.

Ignoring her dying client, Tichelman collected the heroin and needles before stepping over his body to down a glass of wine, according to the yacht's surveillance footage viewed by police. Tichelman then closed the blinds to hide the body.

Hayes was found dead the next day by the yacht's captain, the newspaper reported.

"She showed no regard for the victim," Steve Clark, deputy chief of the Santa Cruz Police, told KXTV. "She showed no attempt to even try to render aid or get aid there to assist him."

Tichelman was arrested after an undercover detective offered her $1,000 in exchange for her services.

Hayes leaves behind a wife and five children. He was a veteran tech-exec in the Google X division, the same team that developed Google Glass.

Tichelman was held on $1.5 million bail. She did not enter a plea on the charges against her.
