Nicole Regina Volmer, 40, was fatally shot in her Austin, Texas, home on Walton Heath Circle in the Onion Creek neighborhood on December 18, 2016. The shooting occurred during an argument with her husband, Michael Volmer. He brought out a gun; he later said the weapon accidentally discharged when he threw it onto the bed, but the bullet’s trajectory was reported to be inconsistent with that account.

Their teenage daughter was present, called 911, and provided information to police. Michael Volmer was arrested and initially charged with murder; he later pleaded guilty to manslaughter. In December 2019 he was sentenced to 20 years in prison. Nicole is survived by four children and her extended family has been supporting them.

If anyone knew Nicole or was familiar with the Onion Creek neighborhood at the time, does anyone have information about the moments leading up to that evening?
