The arrest of a gunman at the scene of the dramatic shooting of Lien Sheng-wen, son of Kuomintang honorary chairman Lien Chan, fails to answer many questions.
Was the shooting politically motivated? Or was it as simple as what the gunman had said - that Lien was merely a wrong target?
Lien, 40, was shot in the face during a campaign rally outside Taipei on Friday night, on the eve of mayoral and council elections in five municipalities in Taiwan. He was not contesting the elections but was a deputy campaign manager for Taipei mayor Hau Lung-bin.
Police overpowered the gunman, Lin Cheng-wei, 48, and found 48 bullets loaded in two cartridges on him.
Asked the reason for the attack, Lin told police he had targeted Lien by mistake. He said he was involved in financial and land disputes with the candidate for Xinbei council, Chen Hung-yuan, and his father, Chen Ming-hsiung, who was at the rally to support his son.
Lien went through more than four hours of surgery to reconstruct his internal facial cavity. The bullet missed his brain, which was the major reason he survived, doctors said.
Lien said Lin's claim of a wrong target was a lie, according to his assistant Hsu Hung-ting, who visited him at National Taiwan University Hospital. 'I clearly heard [the gunman] say my name and swear at me before the shooting,' Hsu quoted him as saying.
