The Department of Special Investigation admits its probe into the death of Gen Romklao Thuwatham, an army officer killed during the 2010 protests, has made little progress.
Nicha Hirunburana Thuwatham, the widow of Gen Romklao, asked Prime Minister Yingluck Shinawatra during their meeting on Tuesday about whether investigators had made any breakthroughs in her husband's case.
Pol Lt Col Wannapong Khacharak, who is in charge of the investigation, said finding evidence is becoming more difficult as time passes. All investigators had obtained so far are conflicting witness accounts of the incident that took place on Din So Road on April 10, 2010.
He encouraged witnesses with any pictures of the scene or who may have filmed armed men suspected of killing Gen Romklao to submit their evidence.
Witnesses say they spotted the armed suspects briefly on Tanao Road.
DSI chief Tarit Pengdith said the agency suspects three armed men were involved in killing Gen Romklao, adding that protesters who saw the men asked them why they were there and carrying weapons. The men replied they came to help the protesters, who then let them go.
"Now, we have no evidence to link them [the armed men] with the killing of Gen Romklao," Mr Tarit said.
