The family of the devoted grandmother killed by a drugged-up e-biker slammed him for leaving her dead 'in the gutter' as he was jailed today. Gloria Stephenson, 86, a mum-of-four, was on a Zebra crossing near her home when Billy Stokoe , 19, hit her at high speed. Newcastle Crown Court heard that Stokoe couldn't brake because he was looking at his mobile phone in his left hand. After spending the day weaving dangerously in and out of traffic, his bike collided with Gloria, killing her instantly.
