VENTURA, Calif. (AP) — A judge decided Wednesday that a Southern California college professor will stand trial for involuntary manslaughter and battery in the death of a Jewish counter-protester during demonstrations over the Israel-Hamas war last year.

Superior Court Judge Ryan Wright judge declared after a two-day preliminary hearing that there’s enough evidence to try Loay Abdelfattah Alnaji, according to the Ventura County District Attorney’s Office.

Alnaji, 51, is accused of striking Paul Kessler with a megaphone in November during a confrontation at an event that started as a pro-Palestinian demonstration in Thousand Oaks, a suburb northwest of Los Angeles.

Kessler, 69, fell backward and struck his head on the pavement. He died the next day at a hospital.

Alnaji was charged with two felonies: involuntary manslaughter and battery causing serious bodily injury, with special allegations of personally inflicting great bodily harm injury on each count, the DA’s office said. If found guilty of all charges, he could be sentenced to more than four years in prison.
