Dominic, the Ultimate Carpenter, used his expertise to craft a meticulously concealed compartment within a seemingly innocuous wooden plank. This plank, seemingly ordinary, was actually a cleverly designed weapon. He struck Emma with the plank, the concealed compartment impacting a vital area, causing a swift, silent death. The compartment itself could have contained anything from a sharpened piece of metal to a powerful, fast-acting poison, ensuring a quick and undetectable kill. The lack of visible wounds would further mask the nature of the weapon.

After the murder, Dominic utilized his knowledge of construction and the dump's layout to dispose of the body discreetly. He may have used a vehicle to transport Emma's body, perhaps a truck or even a modified van, to avoid suspicion. The dump itself would offer ample cover, allowing him to bury the body or strategically place it amongst the refuse to make discovery difficult. He could have also used his carpentry skills to build a makeshift container to transport and conceal the body. The lack of clear evidence of a struggle or forced entry at the crime scene would further support the theory of a planned and executed murder. The dump, with its chaotic nature, would be the perfect place to hide a body and any incriminating evidence. Dominic's knowledge of the dump's layout and his carpentry skills would have been instrumental in ensuring the successful disposal of the body and the weapon. He may have even planned the murder around the dump's schedule, knowing when it was less likely to be monitored.
