Sentencing brought closure but no comfort for the bereaved family and friends.
‘It’s not like the closure I imagined, but I guess it’s the best we could get,’ said family friend Ousman Ba.
Bui, and his friends Gavin Seymour, 16, and Dillon Siebert, 14, had spent weeks planning the attack on the home.
Bui had wrongly identified it after using the ‘Find My iPhone’ app to track the location of his stolen device to the family’s neighborhood.

After this home in a Denver suburb was completely destroyed, killing five members of the Senegalese family who owned the home, authorities immediately suspected that it was a case of deliberate arson

In August 2020, a raging house fire was reported around 2.40 am in the Green Valley Ranch neighborhood, a new suburban development near Denver International Airport. Police officers who approached the house were beaten back by the intensity of the heat

The teen gang bought hockey-style masks from a costume store and were recorded in ghostly surveillance footage approaching the house laden with cans of gasoline on the night of the fire.
Denver police officer Gordon King was among the first on the scene and heard someone trying to unlock the front door from inside with a keypad.
‘Officer King kicked in the front door but was forced away from the door by the extreme heat,’ the arrest warrant for Seymour recorded.
‘Officer King was able to see a small human body approximately three feet inside of the front door. 
‘As Officer King attempted to get the person out it was apparent that the person was not alive and Officer King was forced back by the extreme heat of the fire.’

The three firebugs were caught by surveillance footage as they approached the home, faces covered by hockey masks and carrying cans of gasoline 

They were then able to place Bui, Seymour, and Siebert at the scene through cell phone location data.
Prosecutors said the three tried to cover their tracks and searched online for information on the fire and about the prison sentence for murder.
The trio were arrested in January 2021 and charged with crimes including first-degree murder with extreme indifference, attempted murder with extreme indifference, burglary and assault with a deadly weapon.

Tragic error: The accelerant fueled inferno left little of the house in Green Valley in a misguided arson attack. It claimed the lives of five members of one family sleeping in their beds on August 5, 2020,

Investigators had little to go on until they ordered Google to hand over information on anyone who had searched online for the Truckee Street address in the two weeks before the fire.
Siebert was sentenced in February 2023 to ten years behind bars for his role in the crime.
Seymour pled guilty to second degree murder in March and was jailed for 40 years followed by five years of mandatory parole.
Bui’s legal team announced a deal with the Denver District Attorney’s Office on Friday in which he agreed to 60 years in a state correctional facility in exchange for the DA dropping an additional 60 criminal charges.

Among those killed in the arson were 29-year-old engineer Djibril Diol, who had recently relocated from Senegal, as well as his wife, Adja Diol, and their 22-month-old daughter, Khadija

Bui’s father, Thuan Bui, was in court to see the plea deal announced, telling reporters: ‘We accept it.’
The murdered family were originally from Senegal and Diol had graduated in 2018 from Colorado State University with a degree in civil engineering.
Diol was working for Kiewit construction, and his family were staying with friends at the house until they could get a home of their own.
The murders appalled the city’s tightly-knit Senegalese community and brought condolences from the country’s president.
Family members watched online from Senegal as Seymour was sentenced in March, and Amadou Beye, who lost his wife Hassan and six-month-old Hawa addressed him personally in court.
‘I hope when you die you will die slow and hard,’ he told him.
‘And you will die young. And when you die, I hope you will feel all the pain they did feel when they were dying. And you will feel all the pain that we feel right now.’

Gavin Seymour, [photo], 16 apologized for his role in the murders as he was sentenced to 40 years in March

Nearly two years after their arrest, Dillon Siebert, 14 at the time of the fire and 17 now, was sentenced after he was initially charged in juvenile court with first-degree murder among 47 counts. The others, Kevin Bui and Gavin Seymour, both 16 then, were charged as adults with first-degree murder, attempted murder, arson and burglary.
Seymour who was convicted and sentenced in March to 40 Years, apologized in court and said: ‘If I could go back and prevent all this I would.
‘There is not a moment that goes by that I don’t feel extreme guilt and remorse for my actions. …I want to say how truly sorry I am to the family members and community for all the harm I’ve done.’
Earlier in February 2023, 17-year-old Siebert was sentenced to 7 years of imprisonment during his hearing in Denver District Court for his role in the deadly arson.
Siebert, whose name was not released previously because his case was in juvenile court, pled guilty to second-degree murder in December 2022, after his case was transferred to regular court.
Dillon Siebert was sentenced in Denver District Court to serve seven years in Youth Offender Services as well as a suspended sentence of 26-years should he violate the terms of that sentence.
He was also sentenced separately in Juvenile Court to serve three-years in the Division of Youth Services..

Mourners leave bouquets, stuffed animals and other remembrances on the fence surrounding the shell of the Diol family’s home in the Green Valley Ranch neighborhood of Denver, CO in August 2020

The murders appalled the city’s tightly-knit Denver Senegalese community and brought condolences from the country’s president. Members of the community gather at the scene on August 5, 2020

But Hanady Diol, who lost his son Djibril and daughter Hassan, said he had thought about killing himself after their deaths.
‘This person here, they are talking about 40 or 30 years. That just means there is no justice there. There is no judging that the people who died are human beings.
‘I’m powerless. I’m unlearned, But know that the people you killed they couldn’t even kill a fly,’ he said. 
‘The people you killed were my hope and life. Know you haven’t just killed five people.
‘Myself and their mother; we’re breathing, but we’re dead.’
Bui will return to court for formal sentencing on July 2.
