From another article but relevant here:
Ronnarong Kaewpetch, the President of the Network of Campaigning for Justice (NCJ), led the families of 13 victims to the Crime Suppression Division this afternoon, August 15th, to call for the Division to be responsible for the venue investigation instead of the local police, reasoning that they were afraid of influential people in the area and thought that the police and local government may have conflicts of interest.
The NCJ president brought some evidence to the division officials and demanded them to investigate three concerning issues, including whether there were government officials and/or influential people involved in the entertainment venue that could have some interests or whether the alleged owner, Sia B, who was currently prosecuted was the true owner of the establishment.
