DENVER—Denver District Attorney Beth McCann announced that 17-year-old Dillon Siebert was sentenced today after pleading guilty to murder in the second degree and to using a weapon during a violent crime for his role in an August 2020 arson homicide. 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 today in Juvenile Court to serve three-years in the Division of Youth Services.
During that incident, Djibril Diol (age 29), Adja Diol (age 23) and their daughter, Khadija, a toddler, Hassan Diol, (age 25), and her infant daughter, Hawa Beye were killed. Three family members who were also living at the house survived the fire by jumping to safety from the second story of their Green Valley Ranch home.
“This horrific incident inflicted irreparable harm to these two beautiful families, terrorized Denver’s Senegalese community and devastated the broader community,” said Denver DA Beth McCann. “We believe this disposition is appropriate given Mr. Siebert’s age and his limited role in planning and executing this horrible act.”
The arrest affidavits will remain sealed until Siebert turns 18-years-old. Two other juvenile defendants are being prosecuted in Denver District Court and those cases are ongoing.
