Merv was a local gun trader and con man. He had brown hair along with brown eyes covered with sunglasses. At the time of his death, he wore a dark blue suit, a light blue striped shirt, and a purple striped tie. He also sported a red pocket handkerchief in his suit breast pocket, and a golden pin the shape of a gun.
Merv was found at a motel pinned to the wall by knives. According to Roxie, before dying, Merv was tortured in numerous ways. Because of all the torturing he endured, Roxie came to the conclusion that he was not tortured at the motel, but she was not sure where either. For her, the cause of death was straightforward: Merv was perforated by six knives thrown from a distance. Two of them pinned him to the wall, and the last one struck his heart. Because of how well the knives were thrown, the team came to the conclusion that the killer properly knows how to throw knives.
Killer and motives
The killer turned out to be a con man posing as an Arabian prince, Sheikh Faisal.
Abdullah bin Faisal was infuriated after Amy and the player gathered enough evidence to prove the faux Sheikh guilty of grand homicide due to him assuming he had diplomatic immunity from criminal prosecution in foreign soil. During the investigation, Hannah found out that Faisal was also a con since he was a failed actor in Ivywood per her information audit. Amy took advantage of Hannah's revelation to make Faisal admit to grand homicide, not to mention the assumption of the Sheikh con Faisal cherished throughout his life, but eventually the driving reason for the murder was because of the diamonds he wanted.
The moment Papa Quansah landed in Paradise City, Faisal targeted him so that he could commence a gun smuggling operation for the Middle East--until Merv beat Faisal for the diamonds. Wanting the diamonds like it was something of high importance to him, Amy thought Faisal tortured Merv so that he would surrender the diamonds to him, but Merv was very protective of the diamonds Quansah promised. Faisal wanted everything that benefitted his Sheikh persona, but Amy felt that this would be of use in court, so the player shipped Faisal to face Judge Dante.
Judge Dante wanted to know why Faisal was innocent of the finger cutting that happened in the Mennagio Casino minutes before Merv's demise, but all Faisal wanted to know was where the diamonds were. Faisal placed a lot of hard work to ensure that his Sheikh persona benefitted him financially and physically, much to the chagrin of Merv beating Faisal for the diamonds. Judge Dante had heard enough, so he sentenced the faux Sheikh to 30 years in jail.
