A sex-obsessed Russian student gave a horrifying account of how he strangled his ex-girlfriend and raped her as she lay dying.
Artyom Iskhakov, 19, told Tatiana Strakhova's parents in the appalling online message how her heart was still beating, so he stabbed her and then had sex with her corpse.
He then paused to eat sandwiches, boasting that several hours later he repeated the depraved sex act.
Jealous of 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.
