Now, 25 years later, 44-year-old Vanvilay Hoomphanh and 47-year-old Vienphet Sundara have been charged with his murder.

Court documents state Oudanonh was stabbed multiple times in the neck and died at the hospital.

Witnesses at the dance told authorities the suspects, three Asian men, sped away in a white car.

Not long after, officers found a light-colored car with suspects who matched the description near 300 W. and 900 S.

The officer pulled over the car and found Sundara in the driver’s seat with blood on his hands, face and clothes.

Hoomphanh was a passenger and also had blood on his clothes and the officer said he found a knife with blood on the blade inside the car.

According to the documents, the officer confirmed the men were at the dance earlier that night and the blood DNA on the knife was a match for Oudanonh.

Officials have not confirmed why it took so long to charge these men but said they hope to release more information Wednesday.

Bail for the suspects has been set at $1 million.

Here is the statement from Salt Lake City Police:
