Two Americans have been charged with murder in the death of a Chicago woman whose bloody body was found this week in a suitcase outside an Indonesian hotel, police in the Indonesian province of Bali said Friday.

Heather Mack, 19, and Tommy Schaefer, 21, both of the Chicago area, have been charged with murder in the death of Mack's mother, Sheila von Weise Mack, said Col. Djoko Hari Utomo, Bali's chief of police.

Authorities say the badly beaten body of Sheila Mack, 61, was wrapped in a blood-stained bedsheet and placed in a large hard-sided suitcase. They say a young couple put the suitcase in the trunk of a taxi outside Indonesia's St. Regis Bali Resort on Tuesday and went back into the hotel, telling the cab driver that they would be back.

After a lengthy wait, the cab driver noticed blood and contacted police. Authorities at the South Kuta station in Bali opened the case and found the body, police said.

Heather Mack and Schaefer were arrested after being found Wednesday morning at another hotel about 15 kilometers (9 miles) from the St. Regis, police said.
