The family of a dead Nvidia AI researcher has been left baffled by an official ruling that he committed suicide — and demanded his cremation is halted.

Irfan Al-Hussaini, 32, was found unconscious in his Palo Alto home in July and died eight days later.

His family says the official ruling he killed himself does not make sense, pointing to him delivering a professional presentation hours before he was found.

“So he was fine. Everyone thought he did a good job. Everything seemed normal,” his sister told NBC Bay Area. His friends also doubt he committed suicide, according to a petition calling for justice for him.

“The doctors reported that he suffered from irreversible brain damage due to lack of [blood] supply to his brain for half an hour to an hour.

“Irfan’s colleagues’ statements, the timeline of the 911 call, and what the doctor reported raises serious questions about what conspired that morning,” they wrote.

They noted Al-Hussaini was “very successful” at work, but claimed his marriage was in “shocking disarray.” His family wants his body to be preserved so physical evidence in the case can be preserved.

They went to Sacramento to deliver a formal complaint and emergency petition to California Attorney General Rob Bonta’s office. The cremation is set for Thursday, which his family hopes to stop.

“We fear that important physical evidence will be lost because the body might be [cremated] anytime now, so we really want the Attorney General to step in and intervene and make sure that the body is properly investigated,” his sister, Sarah Al-Hussaini, said.

The Nvidia researcher’s loved ones hope a re-examination is in the works so the circumstances surrounding his death can be determined.

“Irfan’s voice can no longer be heard – but we seek answers, accountability, and justice in his name. Anyone with evidence, firsthand information, or relevant experiences is urged to come forward and help bring the truth to light,” his friends wrote.
