On the morning of November 21, 2025, police were called to a home at 236 Boston Avenue in Waterloo after a report of a shooting around 11 a.m. Officers found 21-year-old Nyavais Johnson suffering from gunshot wounds inside the residence. He was transported to UnityPoint–Allen Hospital and later pronounced dead; the Iowa State Medical Examiner had not yet released a precise medical cause of death.

Investigators treated the death as a homicide from the start. Police secured the scene near East Hanover and Logan Street, processed evidence, and interviewed potential witnesses. Public reports describe a single-victim shooting inside the home but give no detailed account of what happened immediately before the gunfire, whether there was a struggle, or the relationship between Johnson and the person later arrested.

Within days authorities announced an arrest. Detectives identified 31-year-old Jessie James Harmon III and charged him with Intimidation with a Weapon, Prohibited Person in Possession of a Firearm, and Violation of Probation; those charges do not include a specific homicide count in the latest public updates. The investigation remains active, and police are asking anyone with information about the shooting, possible prior disputes, or Harmon’s alleged involvement to contact the Waterloo Police Detective Division or Cedar Valley Crime Stoppers. Does anyone have information about Johnson, what happened at that Boston Avenue home, or the people involved?
