Castro is booked on two murder counts in San Jose.

A booking on two murder counts is an accusation. Marcelino Castro, 28, of San Jose, was booked into the Santa Clara County Jail on suspicion of two counts of murder after police say he flagged down a San Jose officer Saturday, Sept. 19, 2026, about 5:15 p.m. near Lelong Street and West Alma Avenue, where officers found a deceased man, and then described a second homicide near Autumn Parkway and Coleman Avenue, where a second victim was found near the Guadalupe River. An alleged statement to police is evidence for a court, not a conviction, and with the victims not publicly identified and the motive not detailed, the charging paper is what is live.

KTVU, citing the San Jose Police Department, identified him as Marcelino Castro, 28, of San Jose. That report said he flagged down an officer Saturday just after 5 p.m., that officers found a deceased victim in the area of Lelong Avenue and Alma Avenue, and that he then detailed a second homicide that led officers to Autumn Parkway and Coleman Avenue. ABC7, citing a San Jose police news release, reported the time as about 5:15 p.m. and the first scene as the area around Lelong Street and West Alma Avenue, where officers found a dead man. The same release, as ABC7 reported it, said he then allegedly admitted a second killing near Autumn Parkway and Coleman Avenue, and that both bodies were found in different areas near the Guadalupe River. Street-name wording differs between those accounts. Both describe the same Saturday booking. Neither is a verdict.

KTVU reported that the two victims have not been identified and that police have not detailed a motive or the circumstances. ABC7 reported the booking as on suspicion of two counts of murder. A booking on suspicion is an accusation. It is not a finding that he killed either person, and an alleged statement to an officer is not a conviction. All defendants are presumed innocent until proven guilty in a court of law.
