Chilling boast of boy, 13, who mowed down and killed gran, 60, with her own car as he attempted to take it from driveway

A SCHOOLBOY who mowed down and killed a grandmother with her own car made a chilling boast after he was arrested.

Marcia Grant, 60, was struck by the vehicle as the 13-year-old attempted to reverse it out of her driveway in Sheffield in April.

She was left trapped under the car as her husband frantically tried to get the teen - then aged 12 - to exit the motor.

But the boy suddenly reversed at speed - causing foster mum Marcia catastrophic injuries.

When he was arrested, the teen asked police: "Is she dead?";

He then added: "Looks like I got my first kill.

“It was an accident, I swear.”

The boy appeared at Sheffield Crown Court today where he admitted a charge of causing death by dangerous driving.

He previously admitted possession of bladed article, which was specified as a kitchen knife.

The teen was due to go on trial this week charged with murder but his alternative plea today was accepted by prosecutors.

He will be sentenced on December 1 after psychological reports are made.

Police were scrambled to the Greenhill area of Sheffield at around 7.10pm on April 5.

Tragically Marcia could not be saved and was declared dead at the scene.

Tributes flooded in for the foster carer, who was described as a “beautiful soul”.

Her heartbroken family said: “Marcia was a warm, loving and dedicated wife, mother, grandmother, sister and friend and a pillar of her community.

"Her loss has already sent shockwaves through all who knew her or was lucky enough to be included in her orbit.

"We ask for privacy at this time while further investigations are underway and the Family try to come to terms with this enormous loss.”
