A killer who labelled himself "Psycho" after murdering an Indian student has been jailed for life with a minimum of 30 years.
Kiaran Stapleton walked up to stranger Anuj Bidve, 23, in the street in Salford, Greater Manchester, and shot him in the head at point blank range.
Stapleton, 21, had admitted manslaughter on the grounds of diminished responsibility but a jury at Manchester Crown Court rejected that argument and convicted him of murder on Thursday.
Stapleton laughed as he stood over the body of his victim, who he gunned down in the early hours of Boxing Day last year. He also found amusement in police interviews over the murder and regularly grinned and laughed throughout his five-week murder trial.
The defendant beamed as he came into court for the verdict and again towards a family member as he was led from the dock.
Following the verdict, Mr Bidve's father Subhash said Stapleton had "openly laughed at the memory of our son". He said he believed Stapleton should never be released from prison.
His son had arrived in the UK to study micro-electronics at Lancaster University and was visiting Manchester with a group of friends last Christmas. They left their hotel in Salford to queue early for the sales when their paths crossed with Stapleton's.
He calmly walked across the road and repeatedly asked for the time. When someone finally answered he pulled a handgun out of his pocket and fired one shot to Mr Bidve's left temple. Stapleton told one psychologist in prison that he picked out his victim because "he had the biggest head", the court heard.
The day after the murder he booked into a hotel which overlooked the crime scene in Ordsall Lane and then later went to a tattoo parlour and had a teardrop design placed below his right eye - a symbol used by some gangs to mark that the wearer has killed someone.
After he was arrested and charged with murder he made his first appearance at Manchester Magistrates' Court and gave his name as "Psycho Stapleton".
