Roy Valdez, 50, was killed in Fresno, California; his body was discovered under a downtown bridge on February 27, 2017. Authorities said Valdez was homeless at the time and that he had been living apart from much of his family.

Police did not immediately release details about suspects or a motive, and the death remains an unsolved homicide. Investigators reported few witnesses and scarce leads, which has hampered the probe.

If anyone knew Roy, saw someone near that bridge on February 27, 2017, or has information that could help the investigation, please contact the Fresno police.
