20-year-old who intentionally set house fire that killed family of 5 sentenced

DENVER ( KDVR ) — The man accused of setting a house fire that killed a family of five at a Green Valley Ranch home in 2020 was sentenced Tuesday morning to 60 years in prison.

FOX31 listened in on the court sentencing for 20-year-old Kevin Bui, who pleaded guilty to two counts of second-degree murder .

The 60 other charges Bui faced, including first-degree murder, attempted murder, arson and burglary, were dropped by the prosecutor who recommended that Bui be sentenced to 60 years in prison.

Amadou Beye’s wife and daughter were killed in the blaze.

“I just want him to suffer for the rest of his life,” Beye said.

Bui is the final person to plead guilty in the situation. Gavin Seymour, now 19 years old, pleaded guilty to second-degree murder and was sentenced to 40 years in prison. Dillon Siebert was sentenced to seven years in jail as an adult.

Prosecutors have portrayed Bui as the ringleader of the group that started the fire. The son of immigrants from Vietnam, he had been helping his older sister, Tanya Bui , deliver drugs during the time of the Aug. 5, 2020, fire, according to federal court documents.

During the sentencing hearing, Bui was handcuffed and read a handwritten apology.

“I’m sorry. I take sole responsibility. I made a stupid decision,” Bui said in part.

The sister’s enterprise was accidentally discovered when police searched their family’s suburban Denver home as part of the fire investigation, and she is currently serving a nearly 11-year federal prison sentence.

Bui wrongly believed people who had recently robbed him lived in the home after using an app to track his stolen iPhone to the general area, according to prior testimony in the case. Bui admitted to setting the fire only to realize the next day through news coverage that the victims were not the ones who robbed him.

Family and friends of the victims said they did not listen to Bui’s apology.

“We don’t care about how he’s feeling or anything. He did what he did and he will never be able to change it,” Beye said.

The people killed in the fire were from Senegal and part of the immigrant community in Denver.

“We are still emotionally and we will be emotionally impacted for generations to come,” family friend Ousman Ba said.
