A murder accused’s DNA was found on the handle of a mop which had his alleged victim’s blood on, a court was told.
Ryan Gibb, 32, and Cameron Laurie, 33, deny killing James Chadwick on the night of August 31 into September 1 2015.
Evidence was given yesterday at the High Court in Aberdeen by forensic scientist Sarah Jones who carried out an inspection of Mr Chadwick’s flat.
Advocate depute James Keegan QC asked her about samples of DNA taken from clothes Mr Chadwick had been wearing at the time.
She said a mixed DNA profile was found consisting of DNA matching Mr Chadwick’s “together with DNA which, in our opinion, corresponds to DNA types in the profile of Cameron Laurie”.
Ms Jones said blood matching that of Mr Chadwick was found on the bucket and head of the mop.
She added: “We took samples from the apparently blood-free mid-section and top section of the shaft. We obtained a DNA profile which matched that of Cameron Laurie.”
Keith Stewart, representing Gibb, asked the witness if dilute blood staining on the bathroom floor could have been caused by someone being tended to, with blood and water falling to the floor.
Ms Jones agreed but added: “It would appear that the floor had been mopped.”
Brian McConnachie, representing Laurie, asked Ms Jones about blood staining found elsewhere in the flat.
He said: “If Mr Chadwick is lying bloodied and somebody is whipping him with an item maybe 20 times, the blood spatter pattern you found is not consistent with that.”
The witness replied: “There are missing elements I would say.”
Mr McConnachie asked if Laurie’s DNA on Mr Chadwick’s clothes could be explained by him having picked him up and put him on the sofa.
She agreed it could.
Gibb and Laurie are alleged to have murdered Mr Chadwick, at his Holland Street flat, by striking him on the face, punching and pushing him, repeatedly striking him with a dog lead or similar and kicking and stamping on his head and body.
They are further accused of attempting to defeat the ends of justice.
The trial continues.
