New Yorker turned ISIS recruiter — nicknamed ‘Umm Nuteella’ — faces 70 years in prison after judge tosses ‘shockingly low’ sentence

A New Yorker-turned-ISIS recruiter nicknamed “Umm Nuteella” faces up to 70 years in prison after an appeals court tossed her initial “shockingly low” 48-month sentence for boosting the terror organization.

Sinmyah Ceasar, 29, allegedly continued to chat with terrorist contacts — and even solicited money to help an ISIS supporter — while she was out on supervised release following her release from lockup, Brooklyn federal prosecutors said.

“There is simply no other terrorism defendant who compares to the defendant’s history of recidivism, and her persistence and consistency in disobeying the lawful authority of the Court,” the feds wrote in a memo ahead of her upcoming re-sentencing.

Ceasar was infamously sentenced to just four years behind bars in 2019 by the late Judge Jack Weinstein, who claimed that the Brooklyn woman just needed educational and mental health support that would “save her as a human being.”

She had faced up to life in prison after pleading guilty to charges of providing material support to ISIS and obstruction of justice.

But Ceasar served the slap-on-the-wrist sentence and was sprung in July 2020 to begin serving eight years of supervised release.

But the 2nd US Circuit Court of Appeals overturned Weinstein’s decision in August 2021, calling it a “shockingly low” penalty — and ordered that Ceasar be re-sentenced.

Meanwhile, Ceasar blew off a court-ordered appearance on Aug. 25, 2021 after the appeals decision — and cut off her ankle monitoring bracelet in an attempt to flee to Russia because she didn’t want to go back to prison, federal prosecutors have said.

She was arrested days later when she was found hiding out at an auto body shop in New Mexico.

During her 13 month’s out on supervised release, Ceasar “almost immediately” started violating the terms of her release — including calling a known Taliban supporter twice from a landline at a Queens hotel just weeks after she was released from prison, according to the feds.

She also solicited money for an ISIS supporter and repeatedly lied to her probation officer about using social media, which included her liking a post by a user who had the ISIS flag as his profile picture.

Caesar “intended to marry” ISIS wannabe Fareed Mumuni — who is serving a 25-year sentence for planning to attack an FBI agent — but the marriage fell apart after her friend disapproved, according to court filings.

“The defendant repeatedly violated court ordered conditions, and to be clear, admitted to the court that she violated those conditions,” Brooklyn prosecutors Ian C. Richardson said about Ceasar, who pleaded guilty in October 2022 to failing to appear to court.

The admitted ISIS sympathizer was set to be re-sentenced Thursday in Brooklyn Federal Court but Judge Kiyo A. Matsumoto pushed the date back to February after lawyers said they still had to file additional paperwork.

Her defense attorney, Deirdre von Dornum, pushed for the sentencing to be postponed due to “issues of concern” regarding whether or not she violated supervised release.

Prosecutors are seeking a sentence of 30 to 70 years in prison.

They had sought for her to be jailed for a term of 30 to 50 years at the time of her original sentencing in 2019.

Her attorneys said then that Caesar — who was charged with providing material support to ISIS in 2016 – was raped as a child and suffered from PTSD.

The origin of her unusual ISIS moniker remains unclear.
