 Heather Mack, 19, and her boyfriend Tommy Schaefer, 21, both from Chicago, were arrested in Bali on Aug. 13, a day after the body of Sheila von Wiese-Mack was found in a suitcase inside the trunk of a taxi at the St. Regis Bali Resort. Police said the suspects have made separate confessions: Schaefer admitted to killing Wiese-Mack, 62, and Mack admitted helping him stuff her body into the suitcase. "I'm here to represent Heather's unborn child," lawyer Vanessa Favia told reporters late on Wednesday outside the police station where Mack is being detained in Bali's provincial capital of Denpasar. Utomo said Schaefer and Mack, who is three months pregnant, were accompanied by their Indonesian and U.S. lawyers during the interrogations. Attempts to reach the Indonesian lawyers were not immediately successful. The two suspects have not been formally charged with a crime. Utomo said officers hoped to complete their investigation and file their case with prosecutors before the couple’s detention period ends in the middle of October. After they didn't show up, hotel security guards who found blood on the suitcase suggested that the driver take the taxi to the police station, where officers opened the suitcase and discovered the body.  Heather Mack, the daughter of an American woman found dead inside a suitcase on the Indonesian holiday island of Bali, gestures while in custody in a police station in Denpasar August 14, 2014. Wiese said the girl grew more difficult after the 2006 death of her father, James, a highly regarded Chicago jazz and classical music composer.
– Police say suspect Tommy Schaefer has admitted to murdering his girlfriend's mom, a month after her body was found stuffed in a bloody suitcase in Bali. Schaefer, who was arrested along with the victim's daughter, Heather Mack, confessed to killing Sheila von Wiese-Mack, 62, because "he was hurt and offended by the victim's words in an argument with him," police tell the AP. Witnesses reportedly saw von Wiese-Mack arguing with Schaefer, 21, and Mack, 19, about Schaefer's hotel bill the day von Wiese-Mack was murdered, the Chicago Tribune reports. Police say Mack admitted to helping her beau pack up her mom's body before dropping it in a taxi at the St. Regis Bali Resort. The pair then returned to the hotel and allegedly tried to break into von Wiese-Mack's safe-deposit box, which housed their passports and some jewelry, police say. They fled when hotel staff wouldn't assist them. Authorities say von Wiese-Mack suffered blows to the head but died of asphyxiation. Meanwhile, her brother William Wiese says his sister had been enthusiastic about the vacation. "I think she was hoping it would be a fresh start for her and Heather," who had a troubled relationship, he says. He suspects things went sour when Schaefer showed up unexpectedly. In a strange twist, Reuters reports Mack is now three months pregnant and has hired a lawyer to represent her unborn child.
