A wine-fuelled killer driver was found with illicit pills after being moved to Castle Huntly open prison.
Darryn Ferris had only served a third of his nine-and-a-half year sentence for knocking down and killing dog walker Linda Carson when he was moved to the low security jail.
Ferris, 28, had two months added to his total sentence when he appeared at Perth Sheriff Court to admit having 42 etizolam tablets on August 8.
He claimed he was only holding the tablets for another inmate.
His solicitor said: “He agreed to hold onto these tablets for another prisoner for the weekend and the offence came to light. He has been punished within the system.
“He lost privileges for 19 days and was moved to Shotts Prison the next day.
“He will remain there for three to six months until his status is lowered to allow him to return to Castle Huntly.”
The court was told Ferris had a “horrific driving record” which culminated in him being jailed at the High Court in 2016 over Mrs Carson’s death.
Speeding Ferris had downed a large quantity of tonic wine and was “utterly intoxicated” when he struck his 44-year-old victim while she was walking her dog in Motherwell.
Ferris, who abandoned the car and fled the scene, admitted causing death by driving dangerously while under the influence of alcohol and at excessive speeds.
