A man who was found guilty of stabbing his childhood sweetheart and partner of 34 years with a kitchen knife 15 times says he doesn't remember attacking her.
Kim Ashley Prunster, 57, who attacked his partner Amanda Gibbons, 52, on November 12, 2017, faced a Supreme Court jury in Geralton, Western Australia on Friday.
