Castro is booked on two murder counts after a San Jose confession report.

An alleged confession and a double-murder booking are accusations and evidence claims for a court. They are not convictions. A prosecutor's warning that more victims would not be a shock is investigative caution, not a finding that additional killings are proved.

KTVU FOX 2 reported that Castro flagged down a San Jose police patrol officer on Saturday, just after 5 p.m., and said he had killed someone. Officers responded near Lelong Avenue and Alma Avenue and found a deceased male victim. During the investigation, police say Castro told them about a second homicide near Autumn Parkway and Coleman Avenue, and detectives found a second deceased person there. Later coverage described the bodies as near the Guadalupe River area. He was booked into the Santa Clara County Main Jail on two counts of murder. The victims had not been publicly identified as of the cited reporting. Motive and circumstances are still under investigation. An alleged statement to an officer is not a conviction.

On Thursday, Sept. 24, 2026, ABC7 San Francisco reported that Santa Clara County Deputy District Attorney Michael Gadeberg said investigators are still in early stages and that he would not be shocked if there were additional victims. The District Attorney's Office said the suspect knew the first victim, while the second killing appears random. Those are investigative characterizations. They are not findings. Castro was expected to be arraigned Wednesday but refused to appear. ABC7 reported the next appearance is unclear. All defendants are presumed innocent until proven guilty in a court of law.
