Diamond in the Rough is a case featured in Criminal Case as the one-hundred fifty-fifth case of the game. It is the fortieth case of the game's World Edition (Season 3) and also the fourth case to take place in Africa.


Previously, Prince Abioye told the Bureau that SOMBRA was smuggling diamonds through Mazunda. Carmen and the player went to the De Brills's largest mine, only to find Carmen's rival journalist Jude Connelly impaled on a drill bit.

Mid-investigation, the cops rescued a boy named Goodwill Ngele, who had been dangling from the edge of a cliff near Victoria Falls to protest against child labor in the De Brills mines. Later, mine foreman Clayton Rose tried to blow up the crime scene so the company could continue mining. Despite that, the team was able to incriminate journalist and Jude's colleague Olivier Feraud for the murder.

Olivier eventually admitted to killing him in self-defense. He claimed Jude wanted him dead after he had taken a photo of him smuggling an apple-sized diamond. One night, they went to the mine supposedly for research. Jude then attacked him, and—in defense—Olivier activated the drill, juicing his internal organs. Judge Adaku sentenced Olivier to 15 years in prison, with a chance for parole in 5 years.


A Bureau folder containing information provided by the mole.

After the investigation, Goodwill told Michelle Zuria and the player he saw a person in a raincoat throwing a file folder into the falls. They found a Bureau file folder and deduced the mole was scared off when they heard Goodwill. Per Elliot, the folder contained internal information dating back to Europe, thus ruling out Jonah—who joined in Iraq—as the mole. Furthermore, the folder contained dossiers on everyone except Marina, who then denied being the mole.

Meanwhile, Carmen and the player arrested Frida Cruz for smuggling diamonds before she ran away from SOMBRA. She said SOMBRA was smuggling in the mines, so the team went there and found a metal briefcase with an apple-sized diamond inside. Upon interrogation, Clayton said their security cameras caught Lily Karam sneaking in to steal the diamond. Lily then said that a sponsor had asked her to bring the briefcase to the finish line of the race and that she did not know about the diamond.

While Michelle promised to keep an eye on Marina, the team found out that the race's finish line was in Mazunda, so the Bureau followed the 3R racers and the SOMBRA sponsor there.
