Karen Lopez was 22 when she was shot and killed on December 31, 2017, in Houston, Texas. Her body was found after another victim, Robert Cerda, was also shot; the two victims were discovered at different locations around Houston in what investigators described as a double homicide. Reports say Cerda was killed first and Lopez was forcibly taken away and killed later at a separate location.

The case went cold for years with few leads. Years later two men were arrested and charged: Josue Casco, 37, was charged with capital murder and Herbert James Simon, 40, was charged with murder. Casco and Cerda were reportedly acquainted, and Simon was believed to have carried out the killings. Surveillance footage and witness statements were cited in linking the suspects to the scenes, and purchases of items such as gloves and trash bags were mentioned as part of an effort to conceal the crime. The victims had been on a date and were last seen at a local restaurant the evening they were killed.

If anyone knew Karen or Robert, or has information about that night in Houston, please share what might help investigators.
