On January 23, 1857, Sheriff James Barton and his posse of Deputy Charles Daly and Constables William Little and Charles Baker, were killed while courageously pursuing outlaws. This act of service forever shaped the history of law enforcement in Los Angeles County.
In 2025, Sheriff Barton and his posse were honored and commemorated at the San Diego Creek Trail which marks the exact location in which they lost their lives. Sheriff Robert Luna joined the community and city leaders for the unveiling of the Barton Mound Memorial Plaque, honoring the legacy of Sheriff James Barton, the first Los Angeles County Sheriff member to die in the line of duty.

“The courage demonstrated by Sheriff Barton and his posse more than 160 years ago reflects the same bravery shown by the men and women in uniform who serve our communities every day,” said Sheriff Luna.

We are grateful to the City of Irvine for preserving this important piece of history and honoring the sacrifice, heroism, and legacy of those who gave their lives in service. Their courage will never be forgotten.
