Harrison O’Neill Tiernan’s family has remembered him as far more than the young man whose name appeared in news reports during the final months of his life. Raised largely in Bountiful, Utah, Harrison grew up surrounded by parents, grandparents, siblings and an extended family network that remained important to him as he moved into adulthood.
Harrison died on June 20, 2026, at the age of 23. In the weeks that followed, his family and friends gathered in Utah to celebrate his life and share memories of the person they knew away from the headlines.
His Parents
Harrison was the son of Shane and Erika Tiernan.
The couple raised him in Bountiful, Utah, where he spent much of his childhood. Harrison was born in Salt Lake City on December 6, 2002, and his early years were shaped by family connections in Utah.
His parents remained closely connected to him as he grew older and eventually moved away from the area. After spending part of his childhood in Camas, Washington, Harrison returned to Bountiful with his family in 2009.
Following his death, Shane and Erika were among those who publicly remembered their son and expressed gratitude for the support they received from relatives, friends and members of their community.
His Grandparents
Harrison’s family extended across several generations.
His surviving grandparents included Neil and Julie Tiernan and Barbara Shaffer. His grandfather Don Shaffer had died before Harrison.
The presence of several grandparents in Harrison’s life reflects the close family network described in his obituary. Family members continued to gather around his parents and siblings after his death, providing support during an exceptionally difficult period.
For a young person who maintained strong connections to Utah even after moving elsewhere, those extended family relationships were an important part of his background.
His Siblings
Harrison was also a brother.
His obituary identifies Emma as his older sister and Will as his younger brother. The siblings grew up together during Harrison’s years in Utah and Washington before his adult life eventually took him to California.
Although Emma and Will have generally remained outside the public spotlight, they were part of the family circle that remembered Harrison following his death.
The family’s public tributes focused on his personality, interests and relationships rather than allowing the circumstances surrounding his final months to define his entire life.
Growing Up in Utah
Bountiful was an important part of Harrison’s childhood.
He attended Woods Cross High School and graduated with honors in 2021. His upbringing in the area helped establish many of the interests he carried into adulthood.
Harrison developed a passion for skateboarding, motorcycles and outdoor activities while he was young. Those interests later expanded to include surfing and skiing.
His family also described motorcycles as something of a family tradition, giving Harrison another connection with relatives through a shared hobby.
His California Chapter
After graduating from high school, Harrison began pursuing an independent life.
He obtained a Utah real estate license and briefly worked as a realtor before eventually moving to California. In Los Angeles, he developed his artistic abilities and worked as a tattoo artist.
His family remembered him as creative and ambitious. Tattooing became one of the principal ways he expressed that creativity, while music provided another outlet.
He played electric guitar and wrote songs, demonstrating interests that extended well beyond his professional work.
A Wide Range of Interests
Harrison’s obituary portrays someone with an adventurous personality.
Motorcycles were among his strongest interests, while skateboarding remained a passion dating back to his younger years. After moving to Los Angeles, he became interested in surfing and enjoyed the area’s coastal environment.
He also continued returning to Utah for skiing.
Those activities connected different parts of his life: the mountains and outdoor culture of Utah, his family’s motorcycle interests and the beaches of Southern California.
His family also remembered his interest in clothing and fashion. Before his death, he was reportedly working toward creating a clothing brand of his own.
A Difficult Chapter
Harrison’s final year also brought significant public attention.
In March 2026, he was arrested at Miami International Airport after authorities said they found approximately 75 pounds of marijuana inside two checked suitcases. He was facing a Florida cannabis-trafficking charge when he later died.
An arrest is not a conviction, and the publicly available information does not establish a final resolution of that case.
For his family, however, the events surrounding his arrest became only one part of a much larger story.
His Death
Harrison died on June 20, 2026, at 23.
His death left Shane and Erika, his siblings, grandparents and extended relatives facing the loss of a young family member who still had many years ahead of him.
The family’s published remembrance emphasized the qualities they associated with Harrison throughout his life: his creativity, energy, adventurous nature and relationships with the people around him.
They also expressed comfort through their faith as they dealt with the loss.
The Celebration of Life
Harrison’s family held a public celebration of his life in Bountiful in July 2026.
The gathering gave relatives, friends and members of the local community an opportunity to remember him and offer support to his family. Bountiful was a fitting location because it had been one of the central places in Harrison’s upbringing.
The family also expressed appreciation for the community’s kindness during their period of grief.
Rather than focusing solely on the circumstances of his death, the memorial allowed those who knew Harrison to remember his life and the interests that made him distinctive.
His Family’s Legacy
Harrison Tiernan’s family story is rooted in Utah but extends well beyond it.
His parents, Shane and Erika, raised him in Bountiful and supported him as he explored different interests. His grandparents provided another generation of family connections, while his sister Emma and brother Will shared his childhood.
As an adult, Harrison created a life that reflected his artistic and adventurous personality, moving to Los Angeles, pursuing tattoo artistry, making music and enjoying motorcycles, skateboarding, surfing and skiing.
He died at only 23, leaving his family with memories of a life that was still unfolding.
For Shane, Erika and the rest of the Tiernan family, Harrison’s story is ultimately not defined by a single news report. It is the story of a son, brother, grandson and friend whose life touched a wide circle of people and whose memory continues to be honored by the family and community that stood beside him.
