A Chicago man confessed to killing his girlfriend's mother, whose body was found last month in a suitcase outside a hotel in Indonesia, police in Bali tell CNN.
The girlfriend also confessed to being involved and trying to get rid of her mother's body, police say.
Heather Mack, 19, and Tommy Schaefer, 21, have been detained as suspects in the death of Mack's mother, Sheila von Weise Mack, and "it appears that the motive for the killing was because she was against Schaefer's relationship with Heather," Bali police spokesman Hery Wiyanto told CNN.
Formal charges are pending, as the investigation continues.
What exactly happened in room 317 of the St. Regis Bali Resort and the exact role Heather Mack has is still under investigation, said Denpasar police Chief Djoko Hari Utomo.
Evidence includes surveillance video of an argument between the couple and the victim at the hotel and of the two suspects entering and exiting the hotel room, according to Wiyanto.
