A high-end prostitute administered a Google executive with an injection of heroin and, as he began to die, she sipped more from her glass of wine and walked away, police allege.

Forrest Timothy Hayes, 51, a married father of five, was found dead November 23, 2013, aboard his 50-foot yacht in California’s Santa Cruz harbor, according to a police statement.

He had an “ongoing prostitution relationship” with Alix Catherine Tichelman, 26, who has boasted online of having more than 200 client relationships.

Security footage from the yacht shows the scene they describe, police say. “Rather than provide first aid or call 911, Ms. Tichelman proceeds to gather her belongings including the heroin and needles,” the police statement reads, adding that Tichelman stepped over Hayes’ body several times.

The video shows Tichelman leaving the boat and then reaching back to lower a blind, concealing the victim’s body from outside view, police say.

Detectives are also looking into the death of Tichelman’s boyfriend last year in Georgia. At the time, it was ruled an accidental overdose.

At court Wednesday in Santa Cruz, she was charged with manslaughter, administering heroin to another person, administering bodily harm, moving heroin across county lines, possession of heroin, destroying or concealing evidence, and prostitution. A public defender asked that her arraignment in the death of Hayes be postponed until July 16.

Hayes worked on Google Glass

Police came across Tichelman in the course of investigating the death of Hayes, a Google executive who, reports say, worked on the Google Glass project, among others.

Authorities became concerned that she planned to leave the state, so detectives posing as a potential client lured her to an “upscale location” for a July 4 session costing $1,000. She was arrested when she arrived.

Google did not return messages seeking comment. Apple, where reports say Hayes previously worked, declined comment.

“I was really devastated when I heard about it,” Todd Zion, who worked at Google for a short time under Hayes, told The San Francisco Chronicle. “He was a great boss. I never had a chance to thank him.”

‘Nice to talk with someone about killing sprees’

Tichelman describes herself as a model, makeup artist and writer on what appears to be her Facebook page. It says she formerly worked at Larry Flynt’s Hustler Club and studied journalism at Georgia State University in Atlanta.

“It’s really nice to talk with someone about killing sprees and murdering people in cold blood…and they love it too,” a June 28 post on the page reads. “No judgement (sic). Yay! F**k all of that positivity bullsh**. Take a look around you. Life is hard and then you die.”

The profile includes numerous modeling shots of Tichelman, some of them in provocative poses. By midafternoon Wednesday, the page appeared to have been deleted.

Questions surround Georgia death

Tichelman was arrested last year in Atlanta and charged with battery and false report of a crime. The details of that incident were unclear.

Also last year, Tichelman wrote on a website that she dated the owner of the Masquerade Nightclub in Atlanta. In September, the club’s owner Dean Riopelle died. Tichelman was in the house at the time, according to police.

“She was the one who actually called 911,” Capt. Shawn McCarty of Milton, Georgia, police told CNN Thursday. “Her story was: She was in the shower, heard a large crash, and then found him unconscious on the floor.”

The medical examiner ruled it an accidental overdose from heroin and alcohol. “At the time, we never thought anything different,” McCarty said.

Now authorities are taking a new look at that death “to make sure there’s nothing to it,” he said.
