Police have sent the family murder case in Krabi to prosecutors after spending a month collecting evidence and questioning witnesses.
The investigators, led by deputy police chief Pol Lt Gen Chalermkiat Srivorakan, handed over the charge report containing more than 2,300 pages to Somnuek Siangkong, a spokesman for the Office of the Attorney-General, and other prosecutors at the provincial prosecutor office in Muang district of Krabi.
Police have questioned about 70 witnesses to work on the report after Surikfat Bannopwongsakul, alias Bang Fath, and seven other suspects were arrested on July 16 and later charged after killing village chief Worayut Sanglang and seven other family members at his house in Ao Luk district in the province on July 10.
They were charged with conspiring to murder others, attempting to murder others, forcing others to sign documents regarding their title deeds, illegally possessing the firearms of others, illegally carrying firearms, illegally dressing in military-style uniforms, falsely identifying themselves as military officers, and operating a criminal network.
Alleged mastermind Surikfat and accused Khomsan Wiangnon also faced additional charges for colluding to commit premeditated murder and attempting to commit premeditated murder because police believed they had pulled the trigger, killing the eight victims and injuring three others.
Police pointed to the conflict over the land title deeds between Worayut and Bang Fath as the motive.
Mr Somnuek said after receiving the report that prosecutors would take no more than one month to study the case before deciding on the indictment.
All suspects are detained at the Krabi prison.
