Bianca Damanik was last seen on January 12, 2005, when she was abducted by her non-custodial mother, Elfarida Damanik. This occurred two weeks after custodial rights were given to Bianca's father, Robert McConnell.

Elfarida is described as Asian, 5'5-5'6, 110 pounds, with black hair and brown eyes, and has one missing upper tooth. Bianca's parents never married and their relationship only lasted a few months.

Elfarida is believed to have taken Bianca to Jakarta, Indonesia, where she was born and has worked as a nanny. There are warrants out for her arrest for interference with custody and international parental kidnapping, but Indonesia does not recognize American custody orders.

Bianca's case remains unsolved.
