Dunieski Castillo Leyva, 43, was shot and killed in his pickup truck at the Pleasant Hill Apartments on Anken Drive in southeast Austin, Texas, on July 9, 2017. Police say Castillo Leyva and two friends had gone to an apartment after replying to a sexually-oriented ad on Backpage.com; when the services were not provided as expected an argument broke out and the men asked for their money back. As Castillo Leyva attempted to leave, officers report 17-year-old Julian Juan Medrano ran to the front of the truck and fired a round that struck Castillo Leyva, killing him instantly.

Julian Juan Medrano was arrested and charged with murder and held on bond. Detectives indicated additional charges against others involved were expected. The shooting underscores how quickly a complaint over a paid transaction can turn deadly.

Does anyone who was in the Pleasant Hill Apartments area that night or who knew Dunieski Castillo Leyva have information that could help clarify what happened?
