Harjit Singh Nijjar, 24, was stabbed to death in Southall, west London, on May 14, 2011.
He was attacked outside his home at 15 Spikes Bridge Road at around 6am and suffered a single wound to the chest. Mr Nijjar, a business student, died in hospital later the same day.
Saqib Asif Khan, 30 [9/9/80], of Derley Road, Southall, was arrested and charged with murder.
Khan went on trial at the Old Bailey on March 12, 2012. The prosecution claimed that he drove to the scene to demand money on behalf his new lover, an Estonian woman called Olga.
Jurors were told that Olga had agreed to marry Mr Nijjar's housemate Guljinder Singh in return for £4,000. Although the wedding never took place Olga continued to ask for money and recruited Khan to help her.
On the day of the murder, Khan drove to Spikes Bridge Road and confronted Mr Singh and Mr Nijjar, who were unarmed.
During a scuffle, Khan pulled out a screwdriver and plunged it into Mr Nijjar's chest, penetrating the aorta.
On March 20 Khan was convicted of murder and jailed for life with a minimum of 18 years behind bars before parole.
Detective Chief Inspector Tim Duffield of the Homicide and Serious Crime Command said: "Harjit Nijjar was a young man with hopes and ambitions.
"In electing to use violence to settle what had been a minor dispute, Khan robbed Harjit's family and friends of a caring and much-loved person. Our thoughts go out to them at this sad time.
"Acts of violence will not be tolerated on the streets of London and violent offenders will continue to be brought to justice.
"Saqib Khan has the next eighteen years to contemplate his actions on that fateful day, which resulted in a young man losing his life."
Harjit's brother Ranjit said in a letter to murdermap: "I thank the jurors and the Metropolitan Policeand all others who helped me at that sad moment. Khan spoiled the life of my old parents' beloved son. They were much dependent on the earnings of Harjit Singh Nijjar."
