Why did Abraham Papo die?

The Sydney Morning Herald has reported that no one has been charged over the murder of Abraham Papo, the 27-year-old son of a close-knit Melbourne Jewish family, allegedly committed by an Asian man De Jun Zheng. Why did he die?

According to the report on Oct. 8, Zheng worked as a driver for the brothel's prostitutes, receiving $10 for every drop-off. He said he knew Papo because he had visited the brothel two or three times before ''to book a lady.''

But on the night in question, Zheng said Papo had stormed in, sworn, punched him at least once in the face and grabbed mobile phones and, possibly, some money from the till. Zheng said he chased Papo to his car where he got the tyre lever, which Zheng said Papo used to strike him at least once after Zheng demanded the return of the stolen phones. Zheng said he wrestled the lever off Papo, and struck Papo with it at least once.

At 7:43 a.m. on Feb. 12, 2009, about six hours after his brother's death, David signed a police statement saying that before an agitated Abraham had driven to South Melbourne, he had told him he had called Kathy and heard her crying and ''screaming in pain.'' Abraham told David that Kathy had been taken to Sydney and forced to work against her will.

''He said she was being raped and beaten and (told me) that he had to help her,'' David's police statement says. ''He (Abraham then) said that a male had then got on the (Kathy's) phone and threatened him. The guy had said that he would chop him up if he came near her. He told me he then rang an Asian guy that runs a brothel in South Melbourne and had an argument on the phone about Kathy.''

David also told police he had called Kathy on her phone and, in broken English, she had confirmed that she was with ''bad people,'' was being hurt and was unable to talk.

Marco and Deanna Papo are searching for answers after their son's violent death, the newspaper said.
