A Delaware County woman testified Thursday during her murder trial that she shot her boyfriend to defend herself during a physical fight. 35 year old Danielle Weiner of Ryan, Iowa, is charged in Iowa District Court of Delaware County with first-degree murder in the February 8, 2021, shooting death of 27 year old Devon Hierrezuelo of Oak Lawn, Ill. The trial, which began Tuesday with jury selection, is being held at the Dubuque County Courthouse following a motion for change of venue due to pre-trial publicity of the case. Weiner,the only witness called by the defense, took the stand Thursday, saying she acted in self-defense when she fired the shot at Hierrezuelo.
