A Colorado man was sentenced to 40 years in prison after pleading guilty to second-degree murder, becoming the second person to be sentenced in connection with an August 2020 fire that killed five family members.

Gavin Seymour, 19, was sentenced Friday after pleading guilty in January, according to reports from the AP, CBS News and The Denver Post. Seymour is one of three suspects, who were all teenagers at the time of the fire, in an arson attack that killed Djibril Diol, his wife Adja, their 2-year-old daughter, Diol’s sister Hassan and her infant daughter in their Denver home, the outlets reported, citing police.

A second teen, Dillon Siebert, who was 14 at the time of the fire, pleaded guilty last year to second-degree murder and was sentenced to three years in a juvenile facility, followed by seven in an adult detention program, according to the AP.

According to an arrest warrant reviewed by PEOPLE, video footage of the fire captured three masked individuals running from the scene of the fire minutes before large flames could be seen.

Police identified the suspects months after the fire by obtaining a search warrant that asked Google to reveal which had searched for the home’s address, reported the AP.

Police claimed Bui Googled the residence 13 times two weeks before the fire, according to the warrant. A subsequent search of Bui’s Snapchat revealed messages he allegedly sent to Seymour saying that he had been robbed. Police believe the trio had “somehow attributed” the robbery to the home where the Diol family lived and allegedly burned it down as revenge, the warrant stated.

The AP reported that the victims were not related to the people who had robbed Bui, citing police.

“If I could go back and prevent all this I would,” Seymour reportedly said in court, according to the AP. “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.”
