Jayden Harley was a 17-year-old White male from Watertown, South Dakota, and June 10, 2017 began as a day that should have been remembered for celebration. He had graduated from high school earlier that day, and by evening the neighborhood around 4th Avenue Southwest was awake with the ordinary friction of close-living—voices, music, the kind of noise that can feel harmless to one person and unbearable to another.
As night settled in, police were called to the area around 8:50 p.m. after a dispute between neighbors escalated from words into violence. Authorities described it as a confrontation tied to complaints about noise, with bystanders nearby as the argument peaked. A handgun came out, a single shot was fired, and Jayden was struck in the chest. He was rushed to Prairie Lakes Hospital, but the wound was fatal.
Investigators moved quickly that night. Alexis Velazquez of Watertown—31 at the time—was taken into custody and jailed in Codington County. Early reports said he was arrested and charged with second-degree murder, and police noted the weapon involved was a handgun that was licensed to him. What had been a neighborhood dispute was now a homicide case, and the shock rippled through the city as people tried to understand how fast a familiar conflict had turned irreversible.
In court, the case ultimately turned on accountability and the shape of justice after a single trigger pull. Velazquez-Sanchez later entered a guilty plea to one count of first-degree manslaughter, and state officials said the shooting happened outside a Watertown residence. The sentence announced by the South Dakota Attorney General's office was 50 years in prison with 10 years suspended—effectively 40 years to serve—matching later reporting that described him receiving a 40-year prison sentence following the guilty plea.
Years later, the story resurfaced when a judge considered and rejected a request to reduce that sentence. The motion argued that Velazquez-Sanchez had been remorseful and had tried to better himself while incarcerated, and it raised concerns about mental-health treatment in prison. But the court refused to shorten the punishment, and Jayden's mother described the way her life had been upended since the night her son was killed—language that carried the blunt, permanent weight of grief. The original sentence stood, and the case remained what many in Watertown called it from the start: a tragic loss born from a senseless act of violence.
