DeVon Hierrezuelo was 27 when he was shot and killed in a residence in Ryan, Iowa, on February 8, 2021, at about 1 a.m. He was a Black/African American man from Oak Lawn, Illinois, and the shooting occurred in the small Delaware County town.

The person charged in his death was his girlfriend, Danielle Weiner, then 33. She was arrested and charged with first-degree murder. A change of venue moved the case to the Dubuque County Courthouse because of pre-trial publicity. At trial Weiner was the only defense witness and testified she acted in self-defense during a physical altercation. The jury rejected first-degree murder but convicted her of the lesser-included offense of second-degree murder. She was sentenced to 50 years in prison.

Questions remain about the circumstances inside the home that night and how the case was resolved at trial; anyone with information about DeVon or the incident is asked to come forward.
