Valerie Ann Yanske Jackson, a 40-year-old woman of Black River Falls, Jackson County, Wisconsin, passed away on August 8, 2015, in Houston, Texas. She was a loving homemaker and mother of seven children. Valerie's death was part of a tragic mass shooting incident that occurred in Harris County, Texas, near Houston.

On the day of her death, Valerie was held hostage along with her husband, Dwayne Jackson, Sr., and their six children by David Ray Conley III, who was her former boyfriend. Conley broke into their home through an unlocked window and held them captive for approximately nine hours. During this time, he shot and killed Valerie, her husband, and their six children, one by one, in the back of the head. Valerie was the last victim to be shot.

David Ray Conley III was later arrested and charged with capital murder. He engaged in a shootout with responding police officers before surrendering. Conley's motive for the shooting was reportedly a dispute with his ex-girlfriend, Valerie Jackson.

The tragic incident drew significant media attention and led to multiple investigations to understand the circumstances surrounding the shooting. The case highlighted the importance of addressing domestic violence and ensuring the safety of individuals in potentially dangerous situations.

Valerie Ann Yanske Jackson's death was a heartbreaking event that affected her family and the community deeply. Her eldest daughter, Natalie Conley, is her only surviving child.
