The granddaughter of a dog walker slaughtered by a lover with a “desire to kill strangers” has said failings in the killer’s care were “unfathomable”.

Alexander Palmer had been cared for by Norfolk and Suffolk Foundation Trust( NSFT) before piercing 83 -year-old Peter Wrighton 45 eras in August 2017.

Meg Todd said her grandfather’s murder seemed “more like a film dialogue than real life”.

NSFT said it would appreciate engagement Mr Wrighton’s family to discuss concerns.

Palmer’s murder trial heard he had a “desire to kill strangers – dog hikers seemed to be a particular bugbear of his” and had told hospital staff he intended to hurt someone.
