In the small hours of July 5, 2025, in Vallejo, California, Courtney Whitney, 45, female, was lying in bed when a single round pierced the wall of her home and struck her. Officers responded around 1:36 a.m. to the area of Admiral Callaghan Way, where she was found unconscious; despite emergency care at a local hospital, she died later that day. The scene bore the eerie mix of holiday fireworks and gunfire, and investigators initially treated the shot as an apparent stray round that entered
from outside. Neighbors later built a candle memorial outside the Windmill Trailer Court where Courtney Whitney, 45, female, had lived.
The killing marked Vallejo’s eighth homicide of the year and deepened a familiar grief in a city where holiday nights sometimes blur celebration and danger. For days, detectives asked for tips, sifting reports of vehicles and flashes along nearby corridors while friends and family described a quiet night turned catastrophic by a bullet that was never meant to find a person.
On July 18, police arrested Jose Guadalupe Castillo, 42, of Vallejo, in connection with the shooting that killed Courtney Whitney, 45, female. Jail logs placed his bail at $285,000, and prosecutors later filed a murder charge; authorities also noted he is a convicted felon. Even as the exact chain of events remained under investigation, the arrest shifted the case from a mystery of a stray round to a pursuit of accountability in a bedroom killing that had stunned a family and a neighborhood.
In the weeks that followed, accounts coalesced around the same stark outline: a bullet fired amid Fourth of July chaos traveled the wrong arc and entered a home, ending the life of Courtney Whitney, 45, female, as she slept. Detectives continued to piece together trajectories, witness statements and the origin point of the round, building a case that began with a sudden fracture in the night and moved toward a courtroom where the randomness of a holiday shot would be measured against the charge that turned it into a crime.
