Local media reported that Tseng, who comes from an affluent family, has connections to the Bamboo Union criminal organization. He went to the nightclub with friends the day before the attack but was asked to leave by security at the venue after a quarrel with other customers. On his way out, Tseng hit the security guards and threatened payback. On Sunday, Tseng and his girlfriend Liu allegedly took a group of “gangsters” back to the entrance of the nightclub, seeking a fight. An off-duty police detective, Hsueh Chen-kuo (薛貞國), was informed of the incident by his colleague, a police officer surnamed Chuang (莊). Hsueh was beaten to death in front of the nightclub's main entrance soon after he arrived.

Tseng's lawyer Li Wen-chung (李文中) stressed on his behalf that Tseng did not intend to have Hsueh beaten to death. Furthermore, Tseng did not know that Hsueh was a police officer. Li claimed that Tseng only knew some of the attackers.

Even as prosecutors are examining the suspects' testimonies, local media outlets are making speculations of their own. Local media pointed out that the deceased officer had mediated between employees of a nightclub and its customers two years ago, raising the possibility that he moonlighted as a nightclub bodyguard.

According to the United Evening News (UEN), people familiar with police affairs were divided over the nature of Hsueh's appearance at the nightclub. While some officers saw Hsueh's off-duty appearance at the scene as “odd” and not as innocent as some may claim, others pointed out that unorthodox approaches are not uncommon among plain-clothes officers.

Another key piece of information would be the testimony of Chuang, Hsueh's colleague who tipped Hsueh off about the imminent clash between the gangsters and security guards. Chuang was at the scene and beaten along with Hsueh. He escaped from the mob and went to a nearby hospital. However, Chuang has yet to contact the authorities following Hsueh's death, the UEN reported yesterday.

Interior Minister Chen Wei-zen (陳威仁) said that the police will deal with the problem of gangs and arrest the attackers. Taipei Mayor Hau Lung-bin (郝龍斌) vowed to reinforce the investigation of gang-related crimes and called for heavier sentences on such criminals.
