The court in Hefei in eastern China's Anhui province said a verdict against Gu and the family aide accused as an accomplice would be delivered later. Their trial was followed on Friday by the trial of four senior Chinese police officers accused of helping Gu cover up the crime.
Xinhua said Gu accepted all the facts in the indictment, saying: "The tragedy which was created by me was not only extended to Neil, but also to several families." She repeated that her son was in jeopardy but did not say why.
There have been several reports online after the trial that Heywood had threatened Gu's son, Bo Guagua, over a failed business deal. But the details are not known and Bo Guagua was a graduate student at Harvard when the murder took place.
Xinhua said that family aide Zhang Xiaojun had also confessed and said "sorry" to the relatives of Heywood. A guilty verdict is all but assured against the two and carries the potential punishment of ten years in prison up to a death sentence.
