A 25-year-old woman with a lengthy rap sheet surrendered to police Monday over the fatal stabbing of a Staten Island mom who sources say was protecting her 12-year-old daughter – but the suspect’s celebrity attorney argued that’s “not even close to the truth.”  

Jasmin Thompson was joined by Mario Gallucci — who goes by the moniker “Mr. Acquittal” on X — when she turned herself in to face a second-degree murder charge at Staten Island’s 120 Precinct around 9:40 a.m. in connection to the Tuesday social media-fueled slaying of Jennira Roundtree, 43, outside the victim’s apartment building within NYCHA’s West Brighton Houses, cops and sources said.

Thompson, who also faces a weapon possession rap, was ordered held without bail during her Monday arraignment, according to the Richmond County District Attorney’s Office. 

Sources say Roundtree entered the fracas to defend her young daughter, but then became the target.

But Thompson’s attorney — who rose to fame by repping defendants in high-profile violent crimes, and later, through the USA Network TV show “Partners in Crime” — said “that is not even close to the truth.”

“So this is like the modern-day Hatfields and McCoys, where Ms. Roundtree and a group of her followers, we’ll say, had attacked Ms. Thompson’s sister earlier in the day and jumped another one of her friends earlier in the day,” Gallucci told The Post.  

Roundtree had been swinging a golf club at Thompson’s sister – and also badly battered Thompson’s mother, Gallucci claimed. 

“She took a sock filled with locks … I’m talking about [the kind] that you secure a locker with,” the celebrity attorney added. “And she smashed my client’s mother, who is bruised — and I have pictures of the bruise throughout her body, and [she] has a broken hand as a result of that.”

Gallucci described numerous social media videos showing that there were “a bunch of separate little skirmishes going on,” noting that he has not seen a 12-year-old in the footage he’s reviewed so far.

“Nobody deserves to die, but Ms. Roundtree certainly didn’t come into this with clean hands,” he added. “She started the altercation, continued the altercation and my client is looking at using justification as a defense.”

Thompson’s rap sheet includes six prior arrests — mostly for assaults between 2018 and 2019 — as well as chjarges for petit larceny and reckless endangerment, sources said.

She was also busted while in lockup in 2023 for a contraband-related offense, the sources added.

Thompson knifed Roundtree multiple times in her chest during a social media-fueled melee outside the public housing building on Henderson Avenue near Alaska Street, authorities and sources said. 

A 30-year-old neighbor told The Daily News that a group of girls picked a fight with Roundtree’s pre-teen daughter — prompting the mom to intervene.

Roundtree’s friends had initially called the young girl’s older sister for help, but the quick-acting mother got involved, the neighbor said. 

The neighbor said scaffolding obstructed her view of the mayhem, but she heard what happened. She ran downstairs and already saw officers helping remove Roundtree from the scene.

“The police took her,” she said. “When they carried her, I saw she had a lot of blood. I heard her say, ‘I can’t breathe!’ That’s the only thing she said.”

After suffering multiple stab wounds, she was taken to Richmond University Medical Center, where she died, according to police. 

Gallucci and his partner  “Big Lou” Gelormino have made a business taking on infamous cases such as Eric Bellucci’s murder of his parents inside their home in October 2010. 

Bellucci later called himself the “Son of Sam,” a reference to the Big Apple serial killer in the 1970s, and threatened to shoot Gallucci if he pursued an insanity defense for him, the Staten Island Advance reported.

He also represented Michael Cammarata, the estranged husband of a missing Staten Island schoolteacher who prosecutors say teamed up with his six-month pregnant girlfriend to kill his wife, burn her body and hide it in a storage locker in 2019. 

Just last year, Gallucci represented Christopher Gregor, 31, the New Jersey dad convicted of killing his 6-year-old son by forcing him into a bruising treadmill workout.
