A teenage gap-year student was knifed to death in the street in broad daylight by a "laughing" stranger, a jury has heard.
Kieran Crump-Raiswell, 18, was heading to look for a job when Imran Hussain, 27, walked up to him and "without warning" stabbed him, Manchester Crown Court was told.
Witnesses to the shocking scene in Whalley Range, Manchester, said Hussain appeared to be "sniggering" as he ran to his car and drove off, jurors heard. The killing was the second of two street assaults committed on total strangers in January.
Hussain, from Berkshire, drove from his flat in Coventry on January 4 and punched a man in the face in Nottingham and ran off. On January 16, he travelled up to Manchester from Coventry.
He pleaded guilty at an earlier hearing to manslaughter by reason of diminished responsibility and denies murder.
