On January 3, 2009, Robin Wibstad Dunwoody, a 39-year-old nurse, was shot and killed in the parking lot of Wausau Manor nursing home in Wausau, Wisconsin as she arrived for her shift. Coworkers witnessed the attack. Her ex-boyfriend, 54-year-old Walter Lassa of Mosinee, was waiting for her and shot her twice with a shotgun. Lassa fled but was arrested about an hour later.

Dunwoody had ended the two-year relationship two months earlier and had told family members she feared Lassa in the weeks before her death. She was a mother of two sons and was remembered by family as loving and generous. Lassa pleaded guilty to first-degree intentional homicide; at sentencing the judge imposed life in prison with no possibility of parole.

If anyone knew Robin, her routine at the nursing home, or saw activity in that parking lot on January 3, 2009, please share what might help the record.
