Nicolas Garrido-Antunez, 25, was found dead in Omaha on May 5, 2013, the victim of gun violence. Officers discovered his body in the early morning hours with apparent gunshot wounds; the Omaha Police Department has investigated the killing but has not identified those responsible.

The case remains unsolved amid difficulties investigators note in securing witness cooperation and conclusive forensic leads. Omaha’s cold case load—more than 200 unsolved homicides—frames Garrido-Antunez’s death as one of many that have yet to be resolved despite advances such as improved DNA testing.

Anyone with information that could help bring closure to his family is asked to contact the Omaha Police Department. Did anyone in Omaha know Nicolas or see anything that night?
