After ransacking home, suspects used victims' credit cards to buy jewellery Four suspects have confessed to killing a former Phoenix TV vice-president and his family for their money, Xinhua said yesterday. Zhou Yinan was killed along with his wife, his five-year-old daughter, his accountant and a nanny in his home in Futian, Shenzhen, on May 26. Their bodies had stab wounds, but the exact cause of their deaths had yet to be ascertained as investigations continued. Officers from the Shenzhen police had secured confessions from the four arrested on Monday, Xinhua announced yesterday. The three men and a woman arrested had been mahjong-playing friends of Zhou's wife. Xinhua added that the suspects had planned their raid early in May. They gained access to the Zhous' Xintuo Garden home by telling the nanny that they were delivering mineral water for the family. The four then killed the nanny and ransacked the flat, taking cash and other valuables, Xinhua continued. The rest of the Zhou family and the accountant were killed when they returned to the ground-floor unit. The following day, the gang used the Zhous' credit cards to purchase gold and silver jewellery. They also withdrew 50,000 yuan from the victims' bank accounts. The four divided the cash and fled Shenzhen. Shenzhen police deployed more than 160 officers on the case. They quickly arrested the gang members in Changsha in Hunan province , Dongguan in Guangdong province, and Yichang in Hubei on Monday, cracking the case about 30 hours after it was reported to the police. Zhou, 49, joined the Phoenix board in 1996 and left the station three years later to start an advertising agency in Shenzhen. Phoenix TV yesterday issued a statement condemning the killings. 'All colleagues of Phoenix were shocked by Zhou's murder, and expressed their regret and sadness for his death, as well as expressing their anger against such brutal acts,' it said. Meanwhile, a gas explosion shook Shenzhen's Baoan district on Monday when three armed robbers triggered the blast after they were surrounded by police. The trio, carrying choppers, robbed a household in Baoan and tied up the three people in the flat. But one victim managed to alert a colleague using her mobile phone, and police quickly surrounded the building. All six people in the unit were injured.
