PITTSBURGH, Penn. — A father from Castle Shannon, Pennsylvania, was sentenced to 15 to 30 years in prison for setting fire to his home, an act that resulted in the death of his 19-year-old daughter and left his estranged wife with severe injuries. Brian Shelleby, 47, received his sentence on September 10 after pleading guilty to third-degree murder and aggravated arson, almost a year after the tragic incident on September 14, 2025.
The ruling concluded a harrowing chapter for the Shelleby family, following a devastating fire that engulfed their residence on Corbett Drive. In addition to his main sentence, Shelleby was also given a concurrent sentence of five to ten years for aggravated arson, although he was credited for serving 361 days in jail prior to sentencing. His guilty plea spared him from a potentially more severe trial on a first-degree murder charge that could have carried a heavier penalty.
During the sentencing hearing, the emotional toll of the fire was palpable in the courtroom. Carly Shelleby, the mother of the deceased and Brian Shelleby’s estranged wife, recounted the immense pain of losing their daughter, Lakyn. She expressed heartbreak over the decision made by her husband to start the fire, which ultimately claimed the life of a young woman described as intelligent and compassionate. Family members shared their grief, illustrating the divide within the family over Brian’s actions — some supported him, while others condemned his choices.
Reports indicate that the blaze erupted after an intense argument regarding Brian’s presence in the home during their separation. Carly informed him that he could no longer stay, to which he responded with threats of arson. He later admitted to retrieving gasoline in a misguided attempt to convince her to let him stay.
Witnesses recounted a chaotic scene as the fire quickly spread, prompting emergency calls just before 10 a.m. First responders arrived to find flames consuming the house. While Carly managed to escape, she sustained serious burns, and firefighters later discovered Lakyn inside, unresponsive. A firefighter also required medical attention for smoke inhalation during the rescue efforts.
Neighbors described the fire’s rapid escalation, recalling an explosion followed by thick smoke that blanketed the area. Many attempted to save Lakyn, using ladders and smashing windows to call out to her, but their efforts were in vain, leaving them with haunting memories of a young girl they had watched grow up.
Lakyn was a sophomore at the University of Pittsburgh, known for her academic achievements and active participation in her community. She graduated with honors from Keystone Oaks High School in 2024, where she was a National Honor Society member and an accomplished musician, playing the tenor saxophone in her school’s marching band. Friends remember her as a vibrant, energetic individual with a passion for learning and martial arts.
Following the fire, the community came together to mourn, holding prayer services and leaving flowers and candles near the damaged property. This outpouring of grief stood in stark contrast to the unfolding criminal investigation that detailed the destruction of a family home and the arrest of Brian Shelleby, who was himself grappling with the aftermath of his actions.
As the case progressed, prosecutors offered Shelleby a deal to plead guilty, resulting in a shift away from potential first-degree murder charges. On August 10, 2026, he accepted the terms, acknowledging his actions leading to his daughter’s death. At the sentencing, Shelleby did not address the court, but his attorney read a statement expressing his remorse.
Carly Shelleby, focusing her remarks on the loss of her daughter, displayed a photograph of Lakyn and spoke of her vibrant personality and love for butterflies. She emphasized her desire to remember Lakyn not merely as a victim but as a college student and beloved daughter whose promising future was tragically cut short.
The sentencing resolves aspects of Brian Shelleby’s case, but it leaves lingering questions and a profound sense of loss for Lakyn’s family. For them, the 19-year-old remains at the forefront of their memories, a tragic reminder of the day that shattered their lives and the community around them.
