JURORS in New York have convicted Gigi Jordan ​on the lesser charge of manslaughter​ for ​force-​feeding ​her autistic son a ​fatal ​dose of ​prescription drugs​, a conviction that could result in ​as little as five years prison for the pharmaceutical millionaire​.​

​She faced 15 years to life had jurors convicted her of murder.

Jordan let​ out​ a sigh and her lawyer Allan Brenner smiled as the jury forewoman read the favourable defence verdict, following four long days of deliberation.

Each juror was polled and they confirmed their verdict.

Manhattan Supreme Court Justice Charles Solomon thanked jurors for their service and told them they were free to leave and speak openly about the case — though he recommended they not do media interviews.

During the bizarre six-week trial, the defence argued that Jordan, 53, committed the crime in a state of extreme emotional disturbance out of fear her ex-husband was going to kill her and her son would end up with his abusive biological father.

“She did this because she loved him so much she couldn’t bare the thought of him living without her or him being subjected to the life she’d tried to rescue him from,” Brenner said of his client, who faces between five years to 25 years in prison.

“Since that was the only argument made in support of manslaughter the logical conclusion is that that is the argument they accepted. So to that extent it’s sort of a vindication of our position from the beginning.”

Jurors accepted the unusual defence, and the charge carries as little as five years behind bars. Had she been convicted of murder, she would have faced a heftier term of 15 to life.

“Ultimately you had to put yourself in Gigi Jordan’s state of mind,” said one juror, who declined to identify himself.

“But it was clear that she is putting down on paper, all the way back to 2008, a fear of [Jude’s biological father], whether its as valid or not that’s not what we were deciding.”

Even in finding Jordan guilty of the lesser crime, this juror said he couldn’t understand why she resorted to the desperate, tragic act of killing her own kid.

“The woman injected enough pills into her kid to kill Alaska. It’s clear that there’s a lot of stuff going on with her,” the juror said. “I mean you can easily argue that this woman had endless access to resources. If she was that scared, why didn’t she [seek help] and that weighed on me heavily.”

He added: “But when you look at the text messages she’s communicating, there’s a genuine fear, whether it’s valid or not in her opinion. And if those texts would have appeared two weeks before the murder it might have been different, but going back to 2008 there was this fear that manifested.”

Prosecutor Matthew Bogdanos painted Jordan as a cold, calculated killer — not a woman in the throes of an emotional breakdown.

“For Jude Michael Mirra — 8 years, 6 months and 23 days old, with short brown hair and puffy cheeks — there would be no more school, no more hot chocolate, no swimming in Florida, no gymnastics, no chicken fingers. There would be nothing more for Jude. He was dead,” Bogdanos told jurors during his opening.

During the heinous murder, it was business as usual for the killer mom, who transferred $125,000 via email to another account to make sure her checks didn’t bounce — mere feet from her son as his life slowly drained away, Bogdanos said.

She extended her hotel stay and even calmly requested a bottle of water from room service.

A lethargic Jordan was discovered February 5, 2010, lying amid 5,819 pills and an empty bottle of Grey Goose, near her son’s corpse in the $2,300-a-night suite at the swank Peninsula Hotel on Fifth Avenue, the prosecutor said.

After years of trying to cure Jude of the devastating illness that had robbed him of his speech, subjecting him to numerous experimental procedures, she realised he would never get better and decided to kill him, Bogdanos said.

Jordan’s defence lawyer, Allan Brenner, described his client as a doting mother who only committed the horrific crime to spare her son from a worse fate.

She believed her ex-husband and former business partner, Ray Mirra, planned to kill her after she’d discovered he’d stolen millions from her.

Jordan, who was on the stand for three days, insisted Mirra had threatened her life over the phone shortly before she hatched the sick plot.

She feared that Jude would then end up in the custody of his biological father, Emil Tzekov, who she believed had physically and sexually abused him.

But prosecutors pointed out that both Mirra and Tzekov had signed away their parental rights and, even if she died, wouldn’t end up with custody of little Jude. And the man who Jordan believed was plotting to kill her was the only emergency contact listed for Jude at his school.

On the stand, Jordan insisted that she and Jude exchanged thousands of BlackBerry notes — although Jude couldn’t write or speak, according to one of his teachers.

In the notes, Jude claimed he had been abused by 20 family and friends — some involved in a satanic cult — and used remarkably sophisticated language to describe it. “I want to aggressively punish God,” the then-6-year-old wrote, according to Jordan.

It was more likely that Jordan, who held Jude’s arm when he typed, was actually the one who wrote most of the messages, Bogdanos told jurors.

“She did it because she loved Jude,” Brenner told jurors in his closing. “He was then and remains now the one great love of her life. She did it because the burden of the torment that he had been through and the fear that she had been through became more than she could bear. She did it out of love … she is here alone, lost, broken, awaiting your judgment, she is awash in a sea of regret, remorse, sadness, despair.”

As the jury deliberated, Jordan conducted a flurry of TV and newspaper interviews, including with Dr. Phil, CBS and the Wall Street Journal. Justice Charles Solomon was particularly irked by two misrepresentations Jordan made in the press, including falsely claiming she had been offered a plea deal.
