Jeffrey Bryce McMaster, 44, Died Following Medical Emergency While Staying at Santa Rita Jail in Dublin
DUBLIN, CALIFORNIA (June 10, 2026) – A man identified as Jeffrey McMaster has died in custody while staying at the Santa Rita Jail in Dublin.
Alameda County officials are saying that the death took place over the weekend. Deputies were conducting a welfare check and noticed that Jeffrey McMaster was experiencing some type of seizure inside of his cell.
Deputies and jail staff began rendering medical aid as paramedics were called to the scene. Jeffrey McMaster was transported to a local hospital to receive additional treatment.
Later on, he was medically discharged from the hospital and booked back into the Santa Rita Jail. While at the jail, he was undergoing some type of medical screening and asked to go to the restroom.
Deputies heard a noise while he was in the restroom and noticed that he was suffering from another medical emergency. Despite life-saving measures, he was later pronounced dead.
A full investigation remains ongoing at this time.
Liability for Alameda County Inmate Deaths
Jails have a legal obligation to protect inmates from reasonably foreseeable sources of harm. This includes any harm brought about from medical conditions. Every inmate across California and the United States has a constitutional right to receive reasonably adequate medical treatment. Failing to provide inmates with medical treatment is considered a form of cruel and unusual punishment and therefore unconstitutional. There are a number of factors that could contribute to any inmate death.
- Overcrowding: A number of jails across California have faced overcrowding. This can put a serious strain on the quality of care that all inmates receive.
- Training: Jails tend to have very high turnover rates. This can lead to situations where the remaining staff are never especially well trained or experienced.
- Poor Intake: A jail may fail to properly screen an inmate for any serious medical risks they face.
- Poor Communication: A jail may have poor communication between deputies, nurses, and outside hospitals.
If an inmate does not receive the medical treatment that they need, this could form the basis of a constitutional claim. Jails can be liable if they are deliberately indifferent to the serious medical needs of an inmate in their custody who later dies. Deliberate indifference can come in many different forms. This can include situations where jails delay getting any inmate the emergency pair that they require.
Steps to Take After Alameda County Inmate Deaths
Jails across California and the United States have become increasingly deadly in recent years. According to the U.S. Department of Justice, “A total of 4,234 persons died in state and federal prisons in 2019, a 6.6% decrease from the 4,515 deaths in 2018 reported to the Bureau of Justice Statistics’ (BJS) Mortality in Correctional Institutions (MCI, formerly the Deaths in Custody Reporting Program) data collection.” Multiple actions should be taken after any person dies in custody.
- The actions of jail staff leading up to the death should be scrutinized.
- Any autopsy report created after the death should be collected.
- It should be determined if the jail in question has been the subject of any civil rights complaints.
- The family of any inmate who died should seek an independent review by a team experienced in constitutional law.
It could be difficult to know where to begin after a loved one has died in jail custody. To make matters worse, jails are virtually never transparent about how any particular inmate died in custody. In many cases, they will likely label any inmate death as “natural.” But the fact of the matter is that many deaths listed as natural were actually preventable and involved some amount of neglect. This is why it is so important that these incidents are thoroughly investigated by an outside party.
