A Reuters investigation, which drew on information from two unidentified witnesses, found that Muramoto "was shot almost certainly by a high-velocity bullet fired at street level while standing in a street between Thai troops and red shirt protesters." A summary of the Reuters inquiry, reviewed by CPJ, said that Muramoto "was not shot at close range" and that "both troops and protesters had high-velocity weapons at the time of Hiro's death and there were casualties on both sides that night." The findings contradicted initial government assertions that Muramoto had been shot by a UDD sniper positioned on a nearby rooftop.
By December 2010, Thailand's Department of Special Investigation was focusing on security forces as the likely source of fire. Reuters, quoting from a leaked department report, said the death "was caused by a high-velocity bullet as gunfire flashed from the direction of soldiers." Reuters called for the report to be publicly released.
