WEIRD! Man impersonated girlfriend for two weeks after murdering her [PHOTOS]

The 24-year-old, who can only be referred to under South Korean law as Mr Lee, confessed to killing Sunny Kim, 26, on 18 May, two weeks after she disappeared.

It emerged that after Sunny went missing, Lee had been replying to texts from her phone claiming to be her, apparently using her previous correspondence to mimic how she communicated.

‘The way that he text[ed] me was how would my sister would text,’ Sunny’s sister, who asked to be kept anonymous, told BuzzFeed.

‘We think he may have gone through her phone to see how she usually contacts us.

‘It was really shocking to see how someone can really hide what they did in that way.’

It also emerged that on the day Sunny was killed she had accepted a new job. Later that day Lee, pretending to be Kim, declined the offer, telling the employer ‘she was going back to the US to study’.

Lee turned himself into Busan police. He entered with his wrists cut and bleeding and told officers ‘I killed my girlfriend and buried the body. I also tried to kill myself,’ reports BuzzFeed.

Two days later, Sunny was found in a suitcase buried under cement in the hills near her home.

Lee had a history of being violent towards Sunny, her sister said. Lee is due to appear in court at later date.
