Warriena Wright and Gable Tostee
Gable Tostee is an autistic savant with an obsessive compulsive disorder but that didn't stop him from racking up 100 sexual encounters, recording each experience, then boasting about it on bodybuilding.co.
"Ask a guy who has just reached 100 girls slept with" under his username "GT."
"Eventually figured I'd get the 100th out of the way by dropping my standards...I'm lying on the living room couch typing this while she is asleep in my room....I can't sleep until shes gone."
He kept a list of their names and dates and recorded it all and now those tapes are being used in court.
They met on the dating app Tinder and Warriena Wright's life ended that night.
Yesterday, the Brisbane Supreme Court heard a tape of her terror right before she plunged to her death on the 14th floor of Gable Tostee's Gold Coast apartment.
It left no doubt that she was absolutely terrified of Tostee and was driven to what she thought was her only means of escape - climbing over the balcony and somehow gaining access to another apartment.
Her normal voice, which the court heard on Monday - suddenly changed to sheer terror.
One witness, James Evans said "it wasn't just an ordinary scream, it was a terrified scream." He then heard a loud bang and minutes later he saw Tostee running from the apartment building on foot.
Another witness, Nick Casey, visiting a friend in the apartment below, heard her cries for help and when he looked up he saw a woman lowering herself over the balcony. "I heard her say 'I want to go home...help' and I said to her 'go back inside' and then she fell.
The Crown argues that when Tostee refused to let her leave, Ms Wright, fearing for her life, was left with no other option but to escape by climbing over the balcony. And this, they believe, constitutes murder.
In the chilling tape played yesterday, Tostee plies her with alcohol. They seemed to be getting on fine but as the evening wore on, they argue and she turns angry and violent. Tostee is heard to say
"You goddam psycho.... I'm going to let you go, I'm going to walk you out of this apartment just the way you are.....you're not going to collect any belongings.... I'll slam the door on you...you're not going to pull anything or I''ll knock you out, I'll knock you the f*** out. Do you understand? Do you understand?"
Then screaming she yells "no, no, no, no, I want to go home"
He replies "I would, but you've been a bad girl."
A scuffle follows in which Tostee later confesses to his father that he tackled her to the ground and then the sound of a sliding door closing is heard which fits the Crown's argument that he locked her out on the balcony.
Moments later, when she falls, Testee is heard breathing heavily before making a phone call that goes unanswered and then leaves the building. In a later recorded phone call to his father, he tells him he "might have a bit of a situation."
When his father comes to collect him, Tostee explains that they watched a movie and had sex throughout the evening but that she drank heavily. "The last thing I remember is trying to hold her down and she ran out onto the balcony.....I absolutely did not throw her off the balcony, I would never do anything like that."
But the Crown has never argued that Tostee murdered her by throwing her off the balcony. They allege that the obvious terror in her voice prior to being locked out on the balcony constitutes murder, by virtue of the fact she was fleeing for her life when she fell.
And now the ultimate decision rests with six men and six women of the jury.
Edit: Gable Tostee who has Aspergers syndrome, was found not guilty of murder and not guilty of manslaughter.
