Sean Lee King beat, kicked and stomped Jazmin-Jean Ajbschitz to death in an alcohol- and drug-fuelled frenzy Murder victim Jazmin-Jean Ajbschitz (18) whose body was found in her high-rise apartment at Ultimo. SHE was a beautiful girl, his "soul mate" - until he brutally beat her to death in her own home. Sean Lee King, a man capable of "horrifically violent things," today cried in the Supreme Court as he repeatedly apologised to the family of the young woman he murdered, Jazmin-Jean Ajbschitz. Ms Ajbschitz was only 18 when King beat, kicked and stomped her to death in an alcohol- and drug-fuelled frenzy in July 2011. Giving evidence at his own sentence hearing, the 27-year-old said the pair had a "stormy" relationship, but now he would give his own life just to have "Jazy" back. "She had so much life to live ... it hurts knowing it's my responsibility for what I've done," he told his young victim's family. She was my soul mate, I'll never forget Jazy. I wish I could change everything that's happened and give you answers why I've done what I've done. King said he was a "very aggressive person" when he was on drugs and he asked Ms Ajbschitz's family to forgive him for taking the "most loving, beautiful girl away." The 27-year-old claimed at his trial that he was so high on ice when he killed his girlfriend that he didn't know what he was doing, but the jury didn't believe him and he was found guilty of her murder. Crown prosecutor Kara Shead today suggested he was still blaming an addiction for his brutal acts, asking King: "Did the drugs make you do it?" "I'm responsible for her death at the end of the day," he replied. King had viciously stomped on another woman and smashed her head into a car when she was apparently already unconscious in another shocking attack only three months before the murder. The 27-year-old was both on bail and on parole, and was serving a good-behaviour bond for unrelated crimes when he killed Ms Ajbschitz. Earlier her father Shlomo Sol Ajbschitz told the court how his family escaped the horrors of the Holocaust only to have his childhood nightmares re-awakened with his daughter's killing. "Forty years of healing that my new life in Australia had provided has been undone in one brutal act," he said in a victim impact statement. Mr Ajbshitz said he called Jazy, his youngest child and only girl, his "bubelah," Yiddish for "my darling, my baby." "Jazmin suffers no more, but my tears don't dry, " he said. The sentence hearing continues today before Justice Geoffrey Bellew.
