Stella Mwangi’s record label, EMI, confirmed the identity of the victim in a statement on Wednesday.
The 54-year-old Jeff Mwangi Kwirikia died from his injuries after he was run over on county road 454. The driver fled the scene and has not been apprehended.
Police described the vehicle as a black or dark-coloured car, likely a Citroen Berlingo or a Peugeot Partner.
The car was last seen headed in a northbound direction on the stretch of the Trondheim road between Dal and Råholt shortly after the accident at 2pm on Tuesday.
Police said the car’s windscreen was seriously damaged in the crash, while there was also visible damage to the right-hand side of the car.
Police officer Morten Huse said the car had most likely been taken off the road and hidden from sight after the accident.
“That’s why we’re asking the public to monitor whether anyone they know with a car like this suddenly doesn’t have it or has stopped using it,” he told news agency NTB.
Police also appealed for the driver of the car to get in touch with them.
Stella Mwangi, 25, represented Norway at the Eurovision Song Contest in 2011.
