A California socialite convicted of killing two young brothers in a high-speed crash will remain behind bars, after an appellate court upheld her murder convictions.

Rebecca Grossman, co-founder of the Grossman Burn Foundation, lost her appeal as a three-judge panel of California’s Second Appellate District affirmed the jury’s 2024 verdict finding her guilty of murdering 11-year-old Mark Iskander and his 8-year-old brother Jacob.

The ruling means Grossman will continue serving her sentence of 15 years to life in state prison for the 2020 hit-and-run that shattered a family.

Los Angeles County District Attorney Nathan J. Hochman said the outcome reinforces that the convictions were both justified and legally sound.

‘Rebecca Grossman was rightfully convicted by a jury of her peers for the callous murder of two children when she chose to drive up to 81 mph on a residential street after drinking at a bar, knowing full well that this could have deadly results,’ Hochman said in a statement.

‘The legal standard is clear: Driving at excessive speeds through a pedestrian crosswalk after consuming alcohol absolutely demonstrates the requisite state of mind for second-degree murder. The outcome of this case shows that the law applies to everyone, and money or connections offer no immunity from accountability.’

The case centers on a devastating night in September 2020 in Westlake Village, where the Iskander family was crossing a marked crosswalk on Triunfo Canyon Road.

The boys’ mother, Nancy Iskander, testified during the trial that she heard engines roaring as two vehicles sped toward them. 

A California appeals court has upheld Rebecca Grossman’s convictions, rejecting her bid to overturn her two second-degree murder convictions for killing Mark and Jacob Iskander

Mark Iskander was 11 years old when he was killed in the 2020 crash. Jacob Iskander was 8 

She grabbed her youngest child and leapt out of harm’s way, but her other two sons Mark and Jacob who were walking just ahead, were struck.

Her next memory, she told jurors, was seeing her sons lying motionless in the road.

Prosecutors said Grossman was driving her Mercedes SUV at speeds reaching 81mph in a 45 mph zone when she plowed through the crosswalk. 

Evidence showed she continued driving for roughly half a mile after the impact before her vehicle shut down.

In February 2024, a jury convicted her of two counts of second-degree murder, along with two counts of vehicular manslaughter with gross negligence and one count of hit-and-run resulting in death.

Her defense team argued on appeal that the evidence supported, at most, a manslaughter conviction claiming prosecutors failed to prove ‘implied malice,’ a legal standard required for second-degree murder.

But the appellate court rejected that argument, leaving the convictions intact.

At trial, prosecutors had pointed to a pattern of dangerous driving, including a prior warning from a California Highway Patrol officer years earlier after Grossman was cited for speeding at 93 mph. They argued she knew the risks – and ignored them.

Before the tragedy, Grossman had been drinking with her then-lover, former Los Angeles Dodgers’ pitcher Scott Erickson

The prosecution also detailed the circumstances leading up to the crash, alleging Grossman had been drinking earlier in the day and was driving at high speed through a residential area when she struck the boys.

The defense sought to shift blame toward former Major League Baseball pitcher Scott Erickson, who had been with Grossman earlier that day. 

Her attorneys argued Erickson’s vehicle may have first hit the children, placing them in the path of Grossman’s SUV.

Erickson was initially charged with a misdemeanor count of reckless driving, but that charge was later dismissed.

Despite those arguments, jurors found Grossman’s actions met the threshold for murder – a conclusion now upheld on appeal.

The case drew intense public attention not only for its tragic facts but also for Grossman’s high-profile life.

Before her arrest and trial, she was known for her philanthropic work and her role in the Grossman Burn Foundation, tied to a network of medical centers founded by her husband, plastic surgeon Dr. Peter H. Grossman. 

The family lived in an affluent Hidden Hills neighborhood and moved in elite social circles.

But prosecutors emphasized that status did not shield her from accountability.

The boys’ parents, Mark and Nancy Iskander, were with their boys in the crosswalk when the crash happened, with Nancy managing to pull their youngest child to safety before impact

At sentencing, they argued the force of the crash was so severe it was comparable to a Mercedes falling from a 12-story building – a measure of the violence inflicted on the two boys.

Grossman ultimately received a sentence shorter than the maximum prosecutors sought, a decision that left the Iskander family devastated.

Now, with the appeal denied, the criminal case stands as decided – but the legal fight is not entirely over.

The Iskander family has also filed a wrongful death lawsuit against both Grossman and Erickson in a civil case that remains pending.
