POLICE in Kep province yesterday arrested a 19-year-old man suspected of raping and killing a 14-year-old girl, though officials said he had admitted to the killing but not the rape. The victim was reported missing on Monday after she went looking for wild vegetables and didn’t return. Her mother found her body the following day, and reported the case to the local rights group Licadho, said Doeu Sokhom, a monitor for Licadho based in Kampot. Kep police chief Mom Sitha said yesterday that police believed that the suspect killed the girl in an attempt to “lose the proof” that he had raped her.
