Ivan Ortegon-Couoh, a 41-year-old Hispanic/Latino man, was killed on the night of July 25, 2024, along the railroad tracks near the Oakland Coliseum in Oakland, California. He had been living in a small structure between 50th and 66th avenues when witnesses say a person in a white one-piece jumpsuit and a clown mask approached at about 10:20 p.m., and prosecutors later alleged the masked person raised a firearm and fired twice at Ortegon-Couoh. His body also appeared to have been struck by a train when officers arrived.

Early in the inquiry investigators looked at several leads: a man who had walked away with Ortegon-Couoh earlier was detained and arrested on an outstanding weapons warrant but not charged in the killing; another man in his 20s was held on an alleged parole violation but not charged in the homicide; and tips named different people, some of whom were later excluded by DNA testing.

The case went to trial. Jurors acquitted Perez-Munoz of first-degree murder but convicted him of second-degree murder, and of being a felon in possession of a firearm and possession of the sawed-off shotgun; reporting in late July 2026 noted the conviction but did not include a sentence. Does anyone have information about Ortegon-Couoh’s movements near the Coliseum tracks on July 25, 2024, or about the white jumpsuit and clown mask seen that night?
