A break in the case of the Chicago woman killed while on vacation in Bali with her daughter.
The teenage daughter's boyfriend, 21-year-old Tommy Schaefer has confessed to murder.
Indonesian police say he admitted to killing 62-year-old Sheila von Weise-Mack after arguing with her in a Bali hotel room.
Authorities say Schaefer's girlfriend, 19-year-old Heather Mack, who is three months pregnant, witnessed the murder and helped him stuff her mother's body into a suitcase.
Charges have not yet been brought against the couple who have been in police custody since mid-August.
