“My brothers and sisters were kept in cages. I was the only one that slept in a bed. I would even ask my parents if I could sleep in a cage because I wanted to be like the rest of my siblings,” Abba says. “One of my sisters who had Down syndrome, I witnessed my parents shoving a sock down her throat.”

The now 19-year-old says she felt scared and afraid. “Although I was never physically abused, I was emotionally abused by witnessing the abuse,” she says.

She also says she carried guilt for being treated better than her brothers and sisters. “My siblings would always ask me, ‘Oh, Abba. You get treated better than us. Why is that?’ -- “I never knew the answer why. I felt really guilty,” she shares.

When Abba was 10, her parents were arrested and she was removed from the only home she knew. The Gravelles were eventually convicted of four felony accounts of child endangering, two misdemeanor accounts of child endangering and five misdemeanor accounts of child abuse and spent two years in prison.
