Jessica’s family claims she is rude, aggressive, and out of control. Her stepmother, Dori, says she saw Jessica bullied by her older sisters while she was growing up and believes that’s why the 18-year-old became a bully herself.

“When Jessica gets angry, it is very scary,” says Dori. “She escalates from zero to 10 in the blink of an eye.”

Dori says she is concerned for Jessica because no one wants to be around her, let alone live with her.

“I do not play a parenting role to Jessica at all because I’m scared of her,” she says, adding that the behaviors she witnessed when Jessica lived with her has her worried for her stepdaughter’s future.
