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.
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.
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".
Mr Bidve and his wife, Yogini, revisited the crime scene last night to say prayers and lay a bouquet of flowers.
They will return home to India on Friday.
Mr Justice King told Stapleton: "In my judgment, this was no impulsive act on your part. It was a piece of cold-blooded controlled aggression."
He said he had showed a "most callous disregard" in laughing and smirking after he gunned down Mr Bidve and also during the trial.
"You have behaved in a way demonstrating that you are positively boastful about having killed Mr Bidve," he said.
Stapleton nodded before he was led from the dock and then motioned with his hand towards his family to say "Chin up".
