Joshua McKinney, 19, of Houston, Texas, was shot and killed on December 31, 2017 in Baytown, about 30 minutes east of Houston. He had attended Lee College and planned to join the U.S. Marine Corps, and is remembered by family and friends as kind and helpful.

Police say the fatal encounter began during a violent altercation with his girlfriend, 19-year-old Yvonne Ramirez. Authorities allege Ramirez and accomplices attempted to rob McKinney; Ramirez told police she acted in self-defense but investigators found inconsistencies and charged her with murder. She was arrested, held on a $50,000 bond, and Harris County courts handled the case while detectives continued searching for additional suspects.

Anyone who knew Joshua, was in Baytown on the night of December 31, 2017, or has information about others involved is asked to come forward.
