The two families recently agreed to freeze their lawsuit for a few months until they hear from GM about its plans to compensate families of victims who died because of faulty ignition switches. Compensation expert Kenneth Feinberg is working on drafting a plan.
Though they were both in the same car, GM only counts Amy on their list of 13 deaths from ignition switch failures. That's because GM counts only those in the front seat of cars whose airbags didn't inflate.
It's unclear if Feinberg will include victims like Natasha in his plan to compensate victims.
For the two families, however, it's not an easy choice.
Moving forward with the lawsuit will cost them thousands of dollars in legal fees. Plus there's the risk they may get nothing from the lawsuit even though their attorney, Robert Hilliard of Texas, said they and other families he represents have a good case.
Neither girls' parents have said what kind of money they want from GM. However, they want GM to acknowledge its misdeeds killed their daughters, according to interviews with CNN's Poppy Harlow.
"What I want them to do is, for our case, to acknowledge Natasha's death," said Jayne Rimer, Natasha's mother. "I don't need an amount of money, because you will never replace our daughter's life. I want you to acknowledge that my daughter died in your car."
The price tag for corporate negligence
Margie Beskau, mother of Amy Rademaker, said it's impossible to put a value on being robbed of a chance to see her daughter grow up and get married.
"If we get money, fantastic. But it's not gonna bring my daughter back. It's not gonna bring Natasha back," Beskau said.
GM declined to comment on the lawsuit. But spokesman Greg Martin said that GM is "taking steps to treat these victims and their families with compassion, decency and fairness."
