Oak Park police reports over the course of several years show a string of violent incidents committed by a teen against the mother she's charged with killing and stuffing into a suitcase in Bali last week.
Police were repeatedly called to the family's former Oak Park home for reports of Heather Mack attacking Sheila von Wiese-Mack.
In April 2008, police were called to the home in the 900 block of Linden when the then 13-year-old Mack allegedly locked her mother in her room,
In May 2010, von Weisse-Mack told police her daughter threatened to hurt her over a homework dispute.
In February 2011, Mack is accused of pushing her mother, causing her to fall and break her arm.
There's multiple missing persons reports and accusations of Mack breaking household items, biting her mother repeatedly and stealing money and credit cards.
Police were called to the home a total of 86 times for various reasons, but often von Wiese-Mack would not allow police to take her into custody.
Mack, 18, and her 21-year-old boyfriend, Tommy Schaefer, were arrested last Wednesday in Bali's Kuta area, a day after the body of von Wiese-Mack was found inside the trunk of a taxi parked in front of the St. Regis Bali Resort.
Police last week announced the pair were "charged" with murder but later said that wasn't the case. Under Indonesia’s civil law tradition, suspects are only charged during their first appearance in court. Mack and Schaefer remain in custody as the investigation continues but haven't yet appeared in front of a judge. If found guilty of premeditated murder, both could be sentenced to death by firing squad under Article 340 of Indonesia's Criminal Code.
Previous reports put Lois Mack's age at 19. Her Chicago attorney, Michael Elkin, on Monday said she won't be 19 for a few more months.
Elkin also confirmed Monday that his client is two months pregnant and said she's found what appear to be needle marks on various areas of her body but claims she doesn't know how they got there.
She also claims she's been sexually assaulted at least three times in the five days she's been in police custody and complained she was not getting enough water.
An autopsy Saturday found that von Wiese-Mack, 62, died of asphyxiation from a broken nose bone resulting from a blunt blow, said Ida Bagus Putu Alit, head of forensics at Sanglah Hospital in Bali's provincial capital of Denpasar. She also suffered from a broken neck, Alit said.
The couple told investigators that von Wiese-Mack was killed by robbers while they managed to escape, Utomo said.
