Police have named the two Harborough men who died in a fatal crash on the A427 near Dingley on Thursday.
They were Matthew McKnight (41), of Heygate Street, Harborough, and Paul Jones (54), of Warwick Close, Harborough.
Northants police have re-issued an appeal for information about the fatal collision.
The crash happened at about 5.30pm, approximately half-a-mile east of Dingley, when a white Vauxhall Insignia travelling towards Market Harborough left the road and hit a tree.
Mr McKnight and Mr Jones, who both died at the scene, were passengers in the vehicle.
Floral tributes to the two men have been left at the scene as well as police signs appealing for information.
The driver, a 58-year-old man, and another passenger, a 52-year-old man, both also from Harborough, were taken to Kettering General Hospital with chest and back injuries, police said in a statement.
The Mail understand the men all worked for the same company in Northamptonshire and were vehicle-sharing on their way back from work at the time of the incident.
Officers are continuing to appeal for witnesses to the collision and would particularly like to speak to anyone who was travelling in the line of traffic behind the Insignia and who may have information that can help with the investigation.
Witnesses or anyone with information is asked to call the Drivewatch Hotline on 0800 174615 or Northamptonshire Police on the 101 number.
