We are learning more about the prostitute accused of injecting a Google executive with heroin, then leaving him to die.

Alix Tichelman, 26, grew up wealthy but reportedly spiraled down a hole of drugs, sex and damaged men. Her Facebook includes poems about heroin, betrayal and vengeance.

Surveillance video from the boat shows Tichelman converting heroin into liquid, filling up a syringe and injecting herself before injecting 51-year-old Forrest Timothy Hayes. He is then seen raising his hand to his chest and collapsing.

Detectives say Tichelman walked over his body to finish her glass of wine, then cleaned up the scene, removing the drugs and syringe, tidying up, gathering her things and leaving.

One officer described her actions as “glacially cold.”

This wasn’t the first time that Tichelman had been around for a heroin overdose. Two months earlier, she called 911 when her boyfriend, Dean Riopelle, was overdosing. It was ruled accidental, but authorities are now looking into the case again.
