Attorney claims woman arrested in mom's Bali death sexually assaulted in custody

CHICAGO (WLS) -- The attorney for Heather Mack, who was arrested in Bali in the death of her mother, has released a statement concerning his client's health and treatment in Indonesian custody.

Michael D. Elkin issued a statement over the weekend saying that Mack had been threatened with deprivation of food and water and that a translator provided for her was a private detective.

Indonesian police found her mother, Sheila Von Weise-Mack, dead inside a suitcase in a taxi cab Tuesday. Police say they found evidence linking her daughter Heather, 19, and her boyfriend, Tommy Schaefer, 21, to the murder.

Elkin says Mack has not been charged and is two months pregnant, and in a statement Monday, claims his client has been sexually assaulted three times in custody.

"Heather stated in our last conversation that she found what appeared to be needle marks on various areas of her body, without knowledge of the origin of said marks," attorney Elkin said.

Elkin says his client told him she was not getting enough water and claimed she was being given "vitamin pills" but did not know which vitamins they were.

Elkin said the U.S. consulate's staff was present for her call to him, but that she did not tell them about the alleged sex assault incidents

"She quietly whispered into the phone that she was worried about 'saying anything' because the police guard was present in the room," Elkin said I na news release.

Elkin says a team of attorneys, private investigators, and physicians are being assembled in preparation for departure to Indonesia.

If convicted in Bali, the couple could face death by a firing squad. Elkin says the two are innocent.
