Killer socialite Rebecca Grossman is set to have shocking and upsetting encounter behind bars as she begins 15 years to life sentence for murdering two young brothers

Killer socialite Rebecca Grossman faces an anguished jailhouse meeting with the mother of the two young brothers she murdered.  

A heartbroken Nancy Iskander said she wants to see Grossman show remorse for the hit-and-run deaths of her sons, 11-year-old Mark and 8-year-old Jacob, as the family crossed the street in a residential area of Westlake Village, Calif. on September 29, 2020.

'Most people who see me say, "I'm sorry for your loss, I'm sorry for what happened to you.'" Iskander told Fox News. 'She's not in that category. She needs to say, "I'm sorry I killed them." She's not there at all. ... She does not see it.'

Prosecutors said the socialite used her money to 'buy her way' out of taking full responsibility for the hit-and-run deaths of Mark and Jacob Iskander

Iskander continued, 'My plan is to give her a visit in prison, in a few months or maybe a year, and I will ask her that question directly. I will say, "Are you able to say, 'I am sorry I killed them?' This will allow me to forgive, because I need to get through what she's done.'

Prosecutors described Grossman as a 'complete self-serving narcissist' who drove her Mercedes SUV at about 81 mph as she ran over the two boys and kept driving. 

Grossman's attorneys argued it was her ex-lover, former Dodgers pitcher Scott Erickson, who actually hit the Iskander boys on the crosswalk. The two were racing their vehicles, reaching speeds in excess of 70mph in a 45mph speed zone.

Erickson was initially charged with misdemeanor reckless driving, but it was later dropped after the former MLB player issued a public service announcement about the importance of safe driving.

Alexis Grossman, Dr. Peter Grossman, and Nick Grossman provided testimony of support for Rebecca in a 30-minute video that was played in court during Monday's sentencing

Prosecutors asked for a sentence of 34 years to life for two counts of second-degree murder and other charges. On Monday, Judge Joseph Brandolino instead sentenced Grossman to a concurrent sentence of 15 years to life.

Prosecutor Ryan Gould told DailyMail.com that Grossman could be eligible for parole in 7 to 10 years.

Iskander slammed the sentences, alleging the judge treated their deaths as 'one kid' despite 'two different lives' having been lost.

'I don't think I'll ever be able to accept that ... or even understand the judge's point of view,' Iskander told Fox News of the judge's decision.

Grossman, who co-founded a renowned burn unit with her plastic surgeon husband Dr. Peter Grossman, lived a life a privilege and thought her wealth would 'buy her freedom,' prosecutors wrote in an affidavit.

Several former classmates and friends of the Iskander boys provided emotional testimony and asked the judge for the highest possible sentence for Rebecca Grossman

They also said the socialite used dirty tactics, including instructing her 19-year-old daughter Alexis and husband Peter on jailhouse calls to hunt down witnesses and jurors as a way to sway the judge to give her a new trial.

Grossman, who turns 61 on Friday, provided an emotional statement during Monday's sentencing and directly addressed the Iskander family.

'All l've ever wanted to do is to tell you how sorry I am,' Grossman said as she sobbed. 'And I did write. I don't know if the prosecution ever gave them to you. ... They said I would be tampering with witnesses if I reached out to you. ... I'm so sorry I wasn't able to because I was threatened by the prosecutor.

'I just wanted to be a human being. When I couldn't be a human being and talk to you parent to parent, mother to mother... I wanted to leave this world because I didn't want to be here anymore and you have to believe me. And I believe God is in this room right now, and I believe He knows the truth.'

Iskander said Grossman made an anonymous donation of $25,000 toward funeral costs, which she said violated her right to refuse.

Before Grossman was sentenced, her attorney also handed the Iskanders a check in the amount of $47,161.89 for victims' restitution. 

Garrett Dameron, a supervisor in the LA County District Attorney's Office, said Grossman continued to use her money to influence the outcome of the trial.

'She essentially attempted to buy her way out of this,' Damero said to Fox News. 'Never has she once shown a modicum of remorse or sympathy or never has she even hinted at taking responsibility for this. 

He continued, 'And my issue with the judge is he had made comments throughout the trial that he didn’t like the murder charges in this case. Instead of objectively pronouncing [the] sentence as he should’ve, I think he's attempting to legislate from the bench.'

Grossman remains behind bars at a the notorious Downtown LA Twin Towers Correctional Facility as she awaits to be transferred to a women's prison in California.
