Officers from third elite unit join murder hunt
The taskforce probing the mass murders on a Panyu estate has been expanded to include members from a third elite detection unit.
The move came as it emerged that the seven victims on Guangdong's Clifford Estate, including at least one Hong Kong man, were all executed with a shot to the head.
One victim has been confirmed as an American man while the mainland press reported the others killed were women.
Investigators did not rule out the possibility that the murderers targeted only one or two people, but killed witnesses to avoid detection.
Sources at the scene said a dog was also shot at the Seventh Street scene on Monday afternoon.
Detectives suspect that the murders were committed by professional killers with connections to triads.
The chief of Guangdong's Public Security Bureau, Chen Shaoji, appointed two top officers to lead the taskforce.
The pair are Zhang Yongqiang, political commissar of the Public Security Bureau's criminal investigation unit and Hou Tongfen, vice-director of the bureau's serious crime unit.
Their units have cracked many serious cases, including the spate of crimes committed by 'Big Spender' Cheung Tze-keung.
It is understood a team of five to six officials from another division of the criminal investigation unit have been ordered to join the Panyu murder investigation.
