Indeed very soon, after Cao Jiang's corpse was brought back to the Office, the forensic doctor examined his cause of death overnight.
By the next morning, the results were out, and Cao Jiang was indeed smashed to death by that hoe, with the time of death being half a month ago.
Subsequently, Constable Jiang began visiting Ruan Family Village and the village where the Cao Family resided, asking about the people Cao Jiang might have offended during this period, and his personal relationships.
Everyone related to Cao Jiang was questioned one by one. They were asked where they were on the evening of that day half a month ago, what they were doing, and if anyone could verify their whereabouts.
Most of them had alibis, and those conflicting with the timeline were excluded. There were a few without alibis, who had to stay home and be ready for questioning at any time.
Unfortunately, among those who had conflicts with Cao Jiang, there was Ruan Kewei and his gang of rowdy friends.
