Hanane Mouhib, an upstate New York MUSLIM mother, has been charged with murder after she allegedly used a kitchen knife to decapitate her young son Thursday night.

Inside the two-story yellow home, deputies found the decapitated body of 7-year-old Abraham E. Cardenas, according to the Monroe County Sheriff’s Dept.

Officers used pepper spray and a Taser to subdue Mouhib.

At a press conference Friday, Sheriff Todd Baxter described what deputies found as “an extreme, horrific crime scene,” adding, “The word ‘evil’ comes to mind … this is a mother who took her son’s life.”

Investigators say three other people – Mouhib’s husband, his mother and the victim’s 10-year-old brother – were all home during the killing, according to WHAM-TV . It’s believed they were in another room at the time. Authorities have removed the other family members from the home, their whereabouts were not revealed.

Baxter said they are still investigating possible motives in the grisly case. Baxter called the brutal killing an “isolated incident” that didn’t have warning signs or any arguments leading up to the attack.

Brockport Central School District Superintendent Lesli Myers called Abraham “incredibly vibrant, an engaged learner” who was “beloved by his teacher and school community.” His death “completely took us off guard,” she said during a press conference.

Mouhib pleaded not guilty to a charge of second-degree murder Friday morning. She is due back in court April 11.

“Mouhib” is an Arabic name for boys that means “giving, generous.”
