Another Chicago lawyer joins Heather Mack legal team in Bali

BALI, Indonesia (WLS) -- Another local lawyer is traveling to Bali to help represent Heather Mack, the Chicago woman accused of murdering her mother, Sheila von Weise Mack.

Mack's attorney, Michael Elkin, said an additional lawyer from his firm, Vanessa Favia, will be in Bali to assist their client's Indonesian lawyers with the case.

The 19-year-old and her boyfriend, Tommy Schaefer, are accused of killing her mother at an upscale Bali resort. Police found the 62-year-old victim's body inside a suitcase in a taxi cab at the hotel.

Mack and Schaefer could face death by firing squad if found guilty.
