A Chinese man, who has been arrested for the murder of his female compatriot found dead on Jejudo Island in April, committed the crime for money, the police said Sunday.

The police added that the suspect also put the body in the trunk of his car for three days after the murder, looking for the right place to dump the corpse.

The Seogwipo Police Station said Sunday that it will request an arrest warrant for the 33-year-old Chinese suspect for killing the Chinese woman and abandoning the body. The suspect turned himself in on Saturday. 

According to police, the suspect went for a drive with the woman on Dec. 30, 2015, and killed her after having an argument.

Though the suspect told the police that the murder was accidental, the police said he killed her after getting the password of her debit card. He then moved her body from the passenger seat to the trunk of his car and drove around for three days before getting rid of it. The suspect then withdrew a total of 6.19 million won ($5,280) from ATMs using the debit card at least three times.

Police said that the victim, who entered South Korea as a tourist on Oct. 7, 2015, and overstayed the visa-free period to work, and the suspect had a close relationship since meeting through a mobile messenger application. The police said that the male suspect first came to South Korea with a work visa and stayed in the country with an immigration visa after getting married to a South Korean woman in 2010.

The police said because he used a weapon that was already in his car and in light of the brutality of the murder, they will investigate further whether his crime was planned or not.

The body of the dead woman, 22, was discovered by a man gathering bracken near a barley field in the city of Seogwipo on South Korea’s largest island of Jejudo on April 13. It was partially covered by grass and soil, and badly decomposed.
