Earlier this summer, Los Angeles County endured its d**dliest day in law enforcement in more than 160 years when three decorated deputies were ki**ed in a training facility expl*sion.
Nearly two months later, their names and faces remain etched into the hearts of their families, colleagues, and community.
A D**dly Morning in July
On July 19, deputies were working to render safe a device brought to the LA County Sheriff’s Department training facility after being recovered from a Santa Monica garage. But just after 7:30 a.m., the device det*nated. The blast so powerful it was felt for blocks.
“It was like a .1 earthquake,” one witness recalled. “It really shook, and it felt like something was terribly wrong.”
The explosion ki**ed Detective Joshua Kelley-Eklund, Detective William Osborn, and Detective Victor Lemus. Sheriff Robert Luna said: “This is unfortunately the largest loss of life for us as the LA County Sheriff’s Department since 1857.”
Fathers and Mentors Gone Too Soon
The three men brought decades of experience and dedication to the department — and left behind grieving families.
Detective Joshua Kelley-Eklund: a field training officer, narcotics investigator, and father of seven.
Detective William Osborn: a trusted mentor in arson and b*mb squad investigations, survived by his wife, a fellow detective, and their six children.
Detective Victor Lemus: a seasoned K-9 handler and arson investigator, survived by his detective wife and their three daughters.
Together, the deputies represented 74 years of service to Los Angeles County.
A Community in Mourning
An emotional procession followed the tragedy, with colleagues and family members standing shoulder to shoulder as their flag-draped caskets were carried.

Sheriff Luna praised the fallen officers’ dedication: “Today puts a face to how dangerous these men and women’s job actually is on a daily basis and how something can go tragically wrong at any moment.”
Questions Still Unanswered
The investigation into the d**dly blast is ongoing and could take months. Law enforcement sources say a homeowner in Santa Monica was cleaning out a garage when they found items resembling grenades. CBS News reports the sheriff’s b*mb squad took at least one to the training facility, where the team was working to render it safe when it expl*ded.
In the meantime, the department continues to grieve. Vigils and tributes across Los Angeles County have honored the deputies not just as officers, but as fathers, mentors, and friends.
For their families, 16 children now growing up without their fathers, the loss is immeasurable. But their legacies live on as reminders of the dangers law enforcement face and the sacrifices they make to keep communities safe.
