SANTA CRUZ — A high-end prostitute injected lethal doses of heroin into a former Google executive before callously stepping over his body, downing a final swig of wine and then leaving him to die about his yacht, officials said.

The Santa Cruz Sentinel reported Tuesday that surveillance video from the boat shows 51-year-old Forrest Timothy Hayes losing consciousness.

Investigators say the suspect, Alix Catherine Tichelman, makes no effort to help Hayes and instead gathers her belongings and even gulps a glass of wine before leaving.

Hayes was an executive with Google X, the tech giant’s experimental lab, according to USA Today and Forbes. Google X focused on the company’s “moonshot” projects such as Google Glass and driverless cars.

Hayes was a divorced father-of-five and his body was discovered on his 50-foot yacht, Escape, the next day on Nov. 23 at the Santa Cruz Small Craft Harbor.

“The video also shows Tichelman stepping over the victim’s body several times as she is gathering her belongings,” according to a police statement.

“At one point, she steps over the body to finish a glass of wine. Finally, she leaves the boat and reaches back in to lower a blind and conceal the victim’s body from outside view.”

The 26-year-old from Georgia was taken into custody last week after being lured back to Santa Cruz County in a prostitution sting.

She appeared in court in Santa Cruz on Wednesday morning in handcuffs and a red jumpsuit and was charged with manslaughter. She is also charged with administering heroin and possessing heroin.

Police say Tichelman provided heroin for Hayes and the pair met through ‘sugar daddy’ website SeekingArrangement.com, according to News.com.au.

On her Facebook page, Tichelman describes herself as a model and make-up artist, and her social media posts include poems about heroin and her love of TV serial killer Dexter.

In an interview with Fixe Fetish magazine, Tichelman said: “I have always been attracted to the darker side.”

“My parents said by the time I was there I was an intense child, and already liked horror movies.”

On her Facebook page she talks about plans to move to Atlanta, her love of concealed handguns, and on June 28th writes: “It’s really nice to talk with someone about killing sprees and murdering people in cold blood … they love it too. No judgement. Yay! F*** all that positivity bulls**t. Take a look around you. Life is hard and then you die.”
