A forensics expert who examined a vest worn by an officer allegedly stamped on by Sheku Bayoh said she found nothing “of relevance or anything that looked like footwear” on it.
Laura MacPhie, who works at the Scottish Police Authority’s mark enhancement laboratory, examined the police vest worn by PC Nicole Short on the day of Mr Bayoh’s arrest and death in May 2015.
An inquiry into the circumstances of the 31-year-old’s death, how police handled the aftermath and whether race was a factor is taking place in Edinburgh.
Other police officers have previously told the inquiry they saw Mr Bayoh stamping on PC Short after she fell to the ground during the incident in Kirkcaldy.
However other witnesses have cast doubt on whether the stamp took place as the police attempted to detain Mr Bayoh.
A man who watched the arrest from his home said he did not think the stamp could have happened.
Last week, a medical consultant said he would have expected to see more evidence of fractured ribs if this had been the case.
A Scottish Police Federation representative said she saw a mark on the vest, which appeared as if it was “roughly the shape of a shoe”.
‘I did not see anything of relevance’
Giving evidence to the inquiry on Friday, Ms MacPhie described the examinations she carried out as part of an investigation by the Police Investigations and Review Commissioner (Pirc).
Responding to questions from the inquiry’s junior counsel Laura Thomson, Ms MacPhie said she paid particular attention to an “area of discolouration” to the rear of the vest.
Ms MacPhie said: “I gather that what was being asked of as possible footwear was the mark area of discolouration but I did not see anything of any recordable detail within that.”
She said her colleagues had queried whether the mark might be a partial footwear impression and whether she could enhance it and that she was aware of the alleged stamp.
Her statement to the inquiry said a high-intensity light source examination was carried out, adding: “I did not see anything of any relevance or anything that looked like footwear when I carried out my fluorescence exam.”
Forensic expert
Later, Alison Marven, a forensic scientist at the SPA’s forensic services laboratory, showed where marks were found on PC Short’s vest.
She said there was “discolouration” on the front of the inner vest and a black mark on the back of the high-visibility outer vest.
However, her report stated: “The partial mark on the high-visibility vest was found to have insufficient detail for a meaningful comparison to be carried out.”
The vest was passed on to the mark enhancement laboratory for further work.
Photographs of PC Short
Earlier on Friday, SPA scene examiner Judith Harley gave evidence to the inquiry.
She said she took photographs of PC Short, who is now retired, on May 3 and May 8 2015.
The inquiry was shown photos of PC Short’s face, hands, elbows and knees.
Ms Thomson asked why there were no photographs of PC Short’s torso or back.
Ms Harley said: “I can only assume it was never asked for or requested.”
The inquiry before Lord Bracadale continues.
