"Left-handed smoker" appeal - is there a link to male DNA found on cigarette butt in Claudia's car?
Back in 2009, one of the key police appeals was to identify a man - often referred to as the "left-handed smoker" - who was seen with a woman on Melrosegate Bridge at around 5.35am on Thursday 19 March.
The sighting was reported to the police by a passing cyclist who was travelling from Rawdon Avenue towards Heworth Road. The man and woman were on the cyclist’s left hand side near to the substation.
The man was described as about 5ft 6in tall with a skinny build. He was wearing a dark-coloured hooded top with the hood up, and dark-coloured combat trousers with pockets on the side.
He was holding a cigarette in his left hand.
The woman was smaller than the man with mousey brown hair and was wearing a blue, waist-length jacket with buttons and pockets.
Det Supt Malyn said: “Despite numerous high-profile appeals, neither the man or the woman have been traced. We believe it is important to repeat the appeal for any information that could identify these people.
“In particular, the man who smokes with his left hand could be significant to the investigation in relation to the male DNA profile found on a cigarette butt in Claudia’s car.
“Somebody out there knows who this man is and it’s time that they come forward.”
Update 17 April: No new information has been received so far regarding this appeal.
