A man suspected of killing his ex-girlfriend, whose naked body was found in a suitcase in Mapo-gu, western Seoul, has been found dead.

According to Mapo Police Station in Seoul, Monday, the suspect, surnamed Jeong, 31, hanged himself in his apartment in Pyeongtaek, Gyeonggi Province. Officers found a suicide note expressing remorse to his family.

The body of Jeong's ex-girlfriend, surnamed Kim, 23, was found near World Cup Tunnel on Saturday evening, about two weeks after her family reported her missing.

Police analyzed Kim's phone log, finding she had talked to Jeong numerous times in December.

Several hours before her body was found, police visited Jeong's home.

Jeong told them he had dated Kim for five months since July, but that he had not seen her or spoken to her since a phone call on Dec. 15.

Jeong is suspected to have dumped Kim's body following the police visit.
