A Sioux Falls community is mourning the loss of 19-year-old Johnathine Gunn, who died following a single-vehicle crash early Sunday morning on the city’s west side. Gunn’s death has left his family, friends and loved ones grieving as they remember a young man whose life was cut short in the early-morning collision.
The crash was reported at approximately 2:58 a.m. on September 20, 2026, near the intersection of West 12th Street and South Grange Avenue. Emergency crews responded to the area after receiving reports of a serious crash. According to authorities, a 2013 Mazda 3 was traveling eastbound when it left the roadway on the south side while negotiating a left-hand curve.
The vehicle rolled over and subsequently struck a concrete structure. Gunn was identified as the driver and was the only person inside the vehicle at the time of the crash. He sustained serious injuries and was transported to a nearby hospital, where medical personnel attempted to treat him. He later died from injuries sustained in the collision.
Investigators believe excessive speed may have contributed to the crash. Authorities have not determined whether alcohol or drugs were involved, and no further information regarding possible contributing factors has been released. The investigation remains ongoing as officials continue reviewing the circumstances surrounding the collision.
Gunn was also known to family members as Johnathine Chase. Following his death, relatives began making plans for a candlelight remembrance to honor his life and provide an opportunity for family members, friends and others who knew him to gather together.
His sister, Destiny Grant, invited members of the community to attend the candlelight gathering at 7:30 p.m. at the Casey’s location at 12th Street and Grange Avenue, near the site of the crash. Grant described the gathering as something the family had organized on short notice following the unexpected loss.
Grant asked those attending to remain respectful and help keep the gathering peaceful. She said their mother and all of Gunn’s siblings would be present. She also asked anyone who has photographs of Johnathine, including pictures taken with him, to share them with her so the family can preserve those memories.
Gunn’s older brother, Jaden Lantgen, also shared an emotional tribute following his brother’s death. He described Johnathine as the youngest member of the family and the only brother he had. In his message, Lantgen expressed deep regret over losing his brother and reflected on the role he wished he could have played in guiding him.
Lantgen also said he intended to live his life fully in Johnathine’s honor. He shared a promise that the family would rebuild the Honda that Johnathine loved, regardless of how long or difficult the process might be. The plans reflect the family’s desire to preserve something meaningful that reminds them of him.
Grant said her brother would not want his loved ones to spend their time crying over his death. Instead, she said, he would want people to remember him, embrace one another and hold onto the memories they created with him. She emphasized that his presence and memory would remain with the family.
Johnathine Gunn’s death has affected a wide circle of relatives, friends and others who knew him. As the family comes to terms with the sudden loss, loved ones are being encouraged to support one another and remain close during the difficult days ahead.
The Sioux Falls community continues to extend sympathy to Gunn’s family and everyone affected by his death. The investigation into the crash remains open, and additional information may be released by authorities as they continue examining the circumstances that led to the fatal collision.
