An expensive prostitute allegedly injected a married Google executive with a lethal dose of heroin while aboard his yacht, police say. 

Police added that as he was dying the woman stepped over his body to finish her glass of wine. 

The woman, Alix Tichelman, 26, was a high-priced call girl. She was arrested Friday for the death of Forrest Hayes, a 51-year-old married father of five children. His death occured aboard his yacht in Santa Cruz, California last November.

Tichelman posted her services on the website Seeking Arrangement. She had sent e-mails and text messages with Hayes and had met him in person a few times before the Nov. 26 incident.

When they met on Hayes' last day, Tichelman agreed to come to his 50-foot yacht. She brought heroin with her, police said.

After Tichelman injected him, surveillance video on the boat shows that Hayes was suffering from some sort of "medical complication" and losing consciousness. Police say that Tichelman made no attempt to save him or call 911.

In the video, Tichelman is shown gathering her belongings, stepping over his body to finish her glass of wine and then getting off the boat, leaving Hayes to die. Before disembarking, she pulled down a curtain on the boat's window to hide his body from any potential viewers from outside.

The next morning, Hayes body was found by the ship's captain, according to the Santa Cruz Sentinel.

"She showed no regard for him. She was just trying to cover her tracks," Santa Cruz Deputy Police Chief Steve Clark said on Tuesday, reported Mercury News.

Authorities were initially unable to locate Tichelman and spent nine months investigating the incident. They were able to find messages exchanged between Hayes and the call girl.

Clark says that police are aware that Tichelman and Hayes had a previous relationship. He also added that police knew they had spent time together prior to his death.

"This was all set up through text messages and emails. We also know what she did in the aftermath of this. We have her computer records, we know the Google searches that she made, the things she did to try to get herself out of this," Clark said.

Police were able to identify Tichelman in the video and found her fingerprints on the wine glass.

From there, police set up a sting operation to lure Tichelman to a luxury hotel in Santa Cruz. They posed as a client looking to pay $1,000 for sex. She accepted the agreement and arrived at the hotel on the Fourth of July.

Tichelman was arrested at the hotel and booked for suspicion of second degree murder, concealing evidence and drug violations. She remains in jail on a $1.5 million bond.
