A student gave people a running commentary online after killing and strangling his ex-girlfriend then raped her as she lay dying.
Artyom Iskhakov, 19, told her parents in the appalling message how her heart was still beating, so he stabbed her and then had sex with her corpse.
He then stopped to eat sandwiches, boasting that several hours later he repeated the necrophilic act on Tatiana Strakhova.
Riven by envy at his 19 year old ex-girlfriend’s relationship with another man, the talented IT student wrote that his actions were ‘terrible – but I did what I wanted’.
He then hanged himself moments after finishing his post by asking forgiveness from his and her parents, and telling them where to find the bodies.
Tatiana, 19, an A-grade student at one of Moscow’s most prestigious universities, had earlier dated Iskhakov but had ended their relationship.
They continued to share a flat but she had other boyfriends, most recently a man called Igor from St Petersburg.
Iskhakov wrote that it was his obsession with wanting sex with her that drove him to kill her.
A student at elite Bauman University who also worked as a programmer, he admitted in his disturbing social media message that he ‘got tired of listening to her fucking explanations of why she doesn’t want to drink with me – and seeing her flirting with my friend’.
In graphic and shocking testimony about her murder and rape, he wrote: ‘She came home, I was sitting in the kitchen, she walked to her room.
‘I punched her in the face, she fell on the floor. I punched her a few more times, blood started coming from her mouth, and she asked me to leave.
He then described how he felt that her heart was still beating and that he strangled her before slashing her throat.
He then had sex with her corpse before writing what he had done.
He said he then went to make himself a sandwich before sleeping for a few hours before again performing necrophilia on her.
He then wrote a message to Tatiana’s parents saying he was ‘ashamed’, adding: ‘Forgive me for taking your only child from you. I loved her very much.
‘You know, at this very moment I’ve realised what the fuck I did. I feel cold and my hands have started shaking even more.’
He admitted his disgust at having sex with Tatiana’s corpse, adding: ‘Now I can do nothing except kill myself.’
He said: ‘I’ve ruined the happiness of several people, and for what? In the end there is only one emptiness that will swallow me up.’
He claimed he was driven to kill her because of his obsession of wanting sex with her.
