The jury in the civil suit awarded $176 million in damages to the victims' family.
The jury also found that Grossman and Erickson acted with malice in the deaths of Mark and Jacob Iskander, aged 11 and 8, respectively, potentially leading to a punitive damages phase of trial that could lead to further penalties.

The $176 million damages penalty also applies to Grossman's husband, Dr. Peter Grossman. He was a defendant in the lawsuit because he owned the car Rebecca Grossman was driving, and jurors found he had given her permission to drive the vehicle.
It was unclear how the damages would be divided among the three defendants.
The plaintiffs in the civil suit were Nancy Iskander and her husband Karim as well as son Zachary. The lawsuit filed in January 2021 contends that Rebecca Grossman and Erickson, a one-time Los Angeles Dodgers pitcher, had cocktails on Sept. 29, 2020, and the two later engaged in a speed contest along Triunfo Canyon Road until they reached the crosswalk, and the children were struck at about 80 mph in a 45 mph zone by Grossman.
In the criminal trial, Grossman was found guilty Feb. 23, 2024, of two counts each of second-degree murder and vehicular manslaughter with gross negligence and one count of hit-and-run driving.
She was sentenced to 15 years to life in prison.
Erickson did not face any criminal charges in the case.
