Overview
- The shooting took place July 25 at a social‑media‑promoted pop‑up birthday party on a rural property near Hale and Miramonte avenues, where roughly 300 people had gathered and investigators say about seven shots were fired.
- Eighteen‑year‑old Desiderio Romero V was killed and six others were wounded; the medical examiner reported Romero died of multiple gunshot wounds and the injured were expected to survive.
- On Aug. 5 the FBI announced it had joined the Santa Clara County Sheriff’s Office investigation, added technical resources, set up an online digital‑media tip portal and offered up to $20,000 for information leading to arrests.
- Authorities say no suspects or motive have been publicly identified and they are urging anyone with photos, video or information from the scene to upload material to the FBI tipline or call 1‑800‑CALL‑FBI.
- Local officials noted the gathering lacked a county permit and the property owner did not authorize the event, highlighting how unsanctioned pop‑up parties promoted on social platforms can complicate crowd control and accountability.
