HOWELL: In the Netherlands, a 21-year-old American student who was stabbed to death allegedly by her roommate, police found Sarah Papenheim after they received reports of a dispute in her apartment. The 23-year-old roommate has --</s>HOWELL: -- been arrested. Let's get the very latest this hour from Salma Abdelaziz, following the story in the London bureau. What is the latest on this investigation?</s>SALMA ABDELAZIZ, CNN PRODUCER: George, Sarah Papenheim should have been on her way to Minnesota for Christmas next week. Instead, she was tragically found stabbed to death in her apartment in Rotterdam. Police say there was a quarrel in her apartment and, by the time the authorities arrived, it was too late to save the 21-year old. The primary suspect is her male roommate, the 23-year-old man she met in the Netherlands and befriended over their shared love of music. But her mother tells local news that she long worried about the instability of the young man and had even warned her daughter away from him.</s>DONEE ODEGARD, SARAH'S MOTHER: He would have highs and lows. And she noticed that and we had talked and I told her she needed to get out of there because something ain't right.</s>ABDELAZIZ: Her mother went on to tell local news she has cried so much, her tear ducts are dry. And Sarah's local community in the Twin Cities has also been tragically heartbroken over this at the Christmas season. She was an aspiring young musician, her friends called her Thumper because she was so good on the drums. And it's the second time the Papenheim family has seen loss. Sarah's brother died of suicide just three years ago. That inspired the young woman to travel to the Netherlands and study psychology at Erasmus University, where, unfortunately, she lost her life.</s>HOWELL: Salma Abdelaziz, thank you for the reporting. We'll keep in touch. Still ahead, delegates at the COP24 international climate conference in Poland, they are struggling to agree after almost two weeks of talks.
