Dwayne Clifford Jackson Jr was a 10-year-old boy from Houston who was killed on August 8, 2015, in a mass shooting in northern Harris County near Houston. The shooter, identified as 48-year-old David Ray Conley III, forced his way into the home of his ex-girlfriend Valerie Jackson, held her, her husband Dwayne Jackson Sr and their six children hostage, and over about nine hours shot and killed the entire family before a shootout with responding officers.

Conley was arrested and charged with multiple counts of capital murder. He was later convicted and sentenced to life in prison without the possibility of parole. The family had previous contact with Child Protective Services; CPS had investigated complaints about their care going back to 2011, and the children had been returned to the home by March 2014.

Anyone who knew Dwayne Jr., the Jackson family, or has information about the events leading up to August 8, 2015 is asked to come forward.
