Under the Skin is a case featured in Criminal Case, appearing as the seventy-third case of the game. It is the seventeenth case of Pacific Bay and the final one to take place in the Inner City district.
During the investigation, Ramirez stumbled on the operating room where Nikolai was killed and spotted the missing organs. The team concluded that Nikolai's murder and the organ-stealing scheme were linked. Later, Sue Xiong disappeared and Mark McKenzie was revealed to be the organs stealer. Russell deduced that Sue was actually in danger of also being partially skinned, and the team found her in the operating room. Despite the events, the team found enough evidence to arrest businessman Rupert Snow for the murder.
After denying involvement, Rupert admitted to the crime. He was the illegitimate son of Nikolai and Sue, who had abandoned him when the feud started to fight each other. Feeling abandoned, he was determined to end the feud by uniting all the communities in his body. He hired Mark to get Ling Zhang's heart, Radovan's lungs and Angus' spine and transplant them on him. To finish his master plan, he needed halves of his parents' skins. He partially skinned Nikolai with a scalpel but was unable to skin Sue, who helped the police catch him. Judge Dante sentenced him to life in jail.
Post-trial, Frank and the player interrogated Mark about the location of the missing organs. Mark pointed them to the operating room, where they found the organs. Roxie confirmed they were the missing organs and handled them to reputable hospitals. Afterwards, the team confiscated the money Rupert had given Mark for the organs.
After the team helped Yann find his son James, Andrea said that Sergei Yablokov and Sue were going to attend to Nikolai's funeral and work together to end the feud. She then transferred the player to Jazz Town, which had been struck by a hurricane.
