A Chinese man in his thirties has been formally arrested in South Korea after allegedly murdering a 25-year-old Chinese female graduate student and mutilating her body. The victim was found dead at the suspect's residence in Gyeongsan (a city in the southeastern Gyeongsang region), on Tuesday, five days after she was reported missing; the suspect, surnamed Jeong, was apprehended the same day and admitted to the killing during police questioning. Authorities say he disposed of body parts across two distant locations, and police are now considering a psychopathy evaluation given the brutal nature of the crime.
