Dundee man Gary McMillan was stabbed multiple times and died within a “number of minutes” of the fatal blow being struck, a trial has heard.
Arran Fender, 31, is accused of murdering the 44-year-old at the junction of Lawton Road and Lawton Terrace in the early hours of May 16 last year.
He denies the charge and has lodged a special defence of self-defence.
The trial heard from experts, including forensic scientist Sarah Milne and pathologist Dr David Saddler, who were involved in the probe into Mr McMillan’s death.
Both said evidence suggested a silver kitchen knife with a blade more than 12 inches long found at the scene was used to stab Mr McMillan.
The court previously heard the deceased had taken the knife from his kitchen to go and pursue Fender after he appeared outside Mr McMillan’s home and shouted at him in an ongoing feud.
A second knife, found by PC Graham Smith on May 17, was discovered with the blade “stuck into the ground” and the handle poking out in shrubbery in a communal garden to the back of Fender’s home at the time, Glenmarkie Terrace.
The dagger-style knife with a double-edged blade was between a shed and the back boundary wall of the garden, with a leather sheath found nearby.
Both knives had DNA and blood matching the accused and the deceased on them, the trial heard.
Dr Saddler, a senior lecturer in forensic medicine at Dundee University, carried out a post-mortem examination on Mr McMillan on May 17. He said the cause of death was “stab wounds to the chest” and while there were five major wounds on his body, only one was regarded as “fatal”.
That blow had gone into Mr McMillan’s upper left armpit and entered the chest wall between two ribs. It continued through the upper lobe of the left lung and made a “slicing incision” into the upper area of the lung, causing blood to enter his lungs.
Dr Saddler said: “I’d be surprised if someone was successfully treated for this injury.”
He said death would have occurred “in a number of minutes” after the fatal blow being struck.
Other stab wounds were found, with one almost puncturing Mr McMillan’s heart.
The trial, before judge Lady Carmichael, continues.
