The following is from the Contra Costa County Office of the Sheriff:
In-Custody Death Investigation
The Contra Costa County Office of the Sheriff and the Contra Costa District Attorney’s Office are currently jointly investigating an in-custody death that occurred at the Martinez Detention Facility.
On Thursday, January 8, 2026, at about 5:38 AM, Contra Costa Health medical staff at MDF responded to a housing module for a report of head injuries that an inmate apparently sustained as a result of him purposely banging his head while housed in a cell.
Minutes later, the fire department and an ambulance were called to
transport the inmate to a local hospital.
At about 8:30 AM, the inmate was medically cleared at the hospital. He was uncooperative with deputy sheriffs while being transported back to MDF. While at MDF he was given medication by medical staff.
At about 5:48 PM, a deputy sheriff found the inmate unconscious inside his cell. Jail medical staff responded while deputies performed CPR. The fire department and an ambulance also responded and later declared the inmate deceased. The countywide law enforcement involved fatal incident protocol was invoked.
The inmate is identified as 61-year-old Kirk Richardson of Concord. On December 31, 2025, Richardson was arrested by the Concord Police Department for murder. He was booked into MDF on two counts of murder and had been held since that time.
Good riddens MF’r.
Oh well.

It saves taxpayers money
This is one of those cases where suicide was the sincerest form of self-criticism.
I worked along side a person who feel on a job site while working
. He hit the concrete with his head. He was taken to an emergency room and was waiting to be seen by a doctor. One of the emergency triage people in the waiting room asked how he was feeling. He told them that his head hurt from the fall. they gave him some aspirin. He passed away. Severe impact to your head may cause internal bleeding. Aspirin is a blood thinner and can cause the bleeding to bleed more. Please ask your doctor about this. Possible cause of death. Aspirin.
Must have been Kaiser!!
