A South Korean woman apparently mourning the death of her pet dog has committed suicide after leaving a note requesting she be buried with the animal, police said Tuesday. The 25-year-old surnamed Kim was found dead at her home in the southern city of Busan on Monday after apparently burning coal briquettes in the bathroom, a Busan police official told AFP on condition of anonymity. Kim was clutching the dead dog when a co-worker found her body in the bathroom, whose windows and door were sealed with tape, he said, adding the cause of death was likely carbon monoxide poisoning. Kim, who had owned the dog for the past four years, had not been to work since Thursday. The police official said she left a suicide note saying she wanted to be with the dog and to be buried with it.
