The Drainage Ditch in Belinda's House

Amurjit had been murdered brutally buried inside the drainage ditch in Belinda's house taken out of the ditch and then thrown into the water. The cops also noticed burnt ash and char around the ditch which made it obvious that there had been a fire started deliberately at that location something had been burnt there. From this point on this was no longer a possible missing persons case this was a category a case as the cops describe it an investigation into multiple brutal murders. Kenneth Regan and his friend who William Hauncey were nowhere to be found. But I hope you all remember Regan and HaunCEy had a third partner too. Remember there were two men digging the drainage ditch?
