Suggestions that his savage murder this morning by a gunman may have involved women or a gambling debt have quickly been dismissed.
Police now believe that Khun Ae's life was taken because of his bold coverage of two land claims he had labelled as corrupt, purchases at Freedom Beach, south of Patong, and Nakalay Point in Kamala, north of Patong.
Officers undertook to be more specific tomorrow about which of the two controversial projects is likely to be their prime concern.
A party of Pheu Thai officials from Bangkok and Phuket media is due to visit Freedom Beach tomorrow - a trip that Khun Ae would have been on had he lived.
Other Phuket media reported on Freedom Beach but Khun Ae was the first, in his 'Inside Phuket' newspaper.
Deputy Region 8 Police Chief Major General Pisan Juldilok travelled to Phuket today to head the investigation, which has attracted national attention because of Khun Ae's outspoken journalism and his support for red politics on Phuket, a yellow stronghold.
This afternoon, Major General Pisan met with Khun Ae's wife, Jiraporn ''Ji'' Hosakul, who was sitting alongside him in the car when the killers struck. At the meeting were members of the Phuket media and staff from 'Inside Phuket.'
Five teams of police have been dedicated to the case, with security camera footage of the assassination by the motorcycle-riding gunmen in Phuket's main Thepkasattri Road being examined.
Khun Ji noted the numberplate of the motorcycle as it sped away and one of the killers left a pair of sunglasses behind.
If the killers hoped to silence Khun Ae and other journalists, his brutal murder is likely to produce the opposite effect.
