GREEN BAY, WI (WTAQ) – A woman accused of killing a man she was caring for is pleading not guilty by reason of mental disease or defect.
Roni Anderson is charged with arson and felony murder for the June 12, 2015 death of Harold Ambrosius.
Anderson had previously stood mute before a judge, declining to enter a plea. On Tuesday, she changed her plea.
She will now undergo a psychiatric review before returning to court on December 19 to review those results. A trial date has not been set.
According to the criminal complaint, several witnesses and emergency responders told police they pulled up to the fire and saw Anderson kneeling over Ambrosius’ lifeless body in the front yard. Some witnesses told police Anderson wouldn’t let anyone try to help him.
One witness claimed Anderson was ‘incoherent and was wailing.’ The witness called Anderson’s actions ‘not genuine and almost as if it was something she thought she needed to do’ and that she ‘never saw any tears.’
However, Anderson told police she believed Ambrosius started the fire on purpose and she felt that he tried to kill her.
She’s also charged with arson for a separate fire at an office building.
