Sheriff-Coroner David O. Livingston announces that a Coroner’s Jury has reached a finding in the September 15, 2018 death of 61-year-old Dwight Dwayne Dunn of Concord while in custody at the county’s Martinez Detention Facility. The finding of the jury is that the death was the result of natural causes.
The Coroner’s Jury reached the verdict after hearing the testimony of witnesses called by the hearing officer Matthew Guichard.
A transient, Dunn was found unresponsive by a sheriff’s deputy conducting a room check at the jail. Fire crews and an ambulance responded, but he was later pronounced dead. An autopsy and toxicology tests were conducted. Dunn had been booked into jail on September 5 for a parole violation.
A Coroner’s Inquest, which Sheriff-Coroner Livingston convenes in fatal incidents involving peace officers, is a public hearing, during which a jury rules on the manner of a person’s death. Jury members can choose from the following four options when making their finding:
accident, suicide, natural causes, or at the hands of another person, other than by accident.
