On the night he was killed, Thavisha Peiris had agreed to work late at the takeaway pizza chain where he worked, but then asked bosses if he could leave work early because he was feeling ill, police said.
It was agreed that the Sheffield Hallam University graduate could finish after one more delivery - during which he was stabbed to death. Detective Superintendent Lisa Ray described his death as "tragic".
Police said they are not ruling out the possibility the murder of Thavisha Peiris was racially motivated, but said there was "nothing to suggest that's the case".
Detective Superintendent Lisa Ray told a press conference that the pizza worker was wearing a Domino's T-shirt, and said the 25-year-old still had some cash on his person when he died, though police can't yet be sure if anything was taken from the victim.
South Yorkshire Police has told a press conference the force is "open-minded" about the motive behind Thavisha Peiris' murder.
A graduate who was murdered on his last shift at a takeaway pizza chain before beginning a new career in IT was found dead in the driver's seat of his Toyota Yaris by his workmates.
Staff at Domino's in Sheffield became concerned when Thavisha Lakindu Peiris failed to deliver his final order of the evening.
South Yorkshire Police are dedicating a 50-strong team to the murder investigation.
Detectives say they cannot explain the "brutal and shocking death" of a pizza worker who was fatally stabbed as he made his final delivery before starting a career as an IT consultant.
Thavisha Lakindu Peiris was stabbed to death in the Southey area of Sheffield on Sunday evening as he was on his way to deliver a take-away.
Detective Superintendant Lisa Ray, who is leading the investigation, said: "Everything we have learned from his family, friends and workmates at Domino's suggests he was a career-minded, hard-working, bright, articulate and friendly young man who was very much planning his future.
"To date, we have found no explanation for his brutal and shocking death. I need to hear from anyone who knows anything about his murder."
