Alleged Call Girl Pleads Not Guilty in Death of Google Exec

— -- The alleged call girl accused of injecting a Google executive with a lethal dose of heroin aboard his yacht pleaded not guilty to manslaughter charges today.

Alex Tichelman, 26, appeared in court in a red jumpsuit and shackled for her arraignment on manslaughter, drug and prostitution charges for her alleged role in the death of Google employee Forrest Hayes, 51, in November 2013.

According to police, a surveillance video showed her injecting Hayes with a needle and then, when he became unresponsive, stepping over his body on the floor to leave without ever calling for help.

Hayes was a former Apple employee and had five children.

Tichelman's attorney, Larry Biggam, said in a statement after court that he did not believe it was an intentional crime.

Police said they discovered the surveillance video in recent weeks and arrested Tichelman July 4. In the days before her arrest, she had ostensibly written about killing sprees on her Facebook page, including that it was "really nice to talk with someone about killing sprees and murdering people in cold blood...and they love it too."

"No judgement [sic]. Yay!” she wrote. “F*** all of that positivity bulls***. Take a look around you. Life is hard and then you die."

Hayes' family did not appear in court. Tichelman's mother, father and sister did appear but did not comment on the case.
