The accomplice of "bunny boiler" Sarah Williams reportedly feared the murderer would kill her too by lacing her food with prawns.
Katrina Walsh is said to have believed Williams, who stabbed love rival Sadie Hartley to death after shooting her with a 500,000 volt stun-gun, would frame her as the suspect in a murder-suicide plot.
Walsh's paranoia was revealed as footage emerged of the moment Williams was woken in her bed by police and arrested over the businesswoman's murder.
