Yet another inmate has died under uncertain circumstances at the Monterey County Jail, this time a 29-year-old Carmel Valley man named David John Sand who had suffered from severe schizophrenia for the past 10 years, according to his father, Eric Sand. David died on Saturday, Nov. 12. The cause of his death is unknown.
According to Sand, Sheriff’s detectives told him David was found in his jail cell unresponsive. Sand says detectives told him David had cut himself and it appeared he was attempting to write a message in blood on the wall. Sand does not know what was written. He was told photos were taken.
Sand also says he was told by detectives that an initial autopsy performed two days later on Monday, Nov. 14, showed David had an enlarged heart and his lungs were overweight, indicative of drug use. Sand says outside of jail David's drug of choice were methamphetamines. David had been in jail since early May.
Final autopsy results will take some time, Sand says. He plans on having a second, independent autopsy done. Sand wants to speak out because he believes his son's death was preventable.
"David could have been saved on any number of occasions and the county missed many opportunities to treat his schizophrenic condition," Sand says.
Monterey County Sheriff’s Capt. Joe Moses, who oversees the jail, said he was unable to comment. All questions were referred to County Counsel Les Girard. “No comment at this time,” Girard says via text. All circumstances surrounding the death are unknown, he says.
David was diagnosed with schizophrenia about a decade ago and has been in and out of psychiatric treatment centers as well as jails in Monterey, Santa Clara and Stanislaus counties, Sand says. He also spent time homeless on the streets of Chinatown in Salinas.

Most of the time spent in jails came about because of parole violations, Sand says, “as [David] was severely schizophrenic and could not comprehend what he was told to do.”
David’s latest stay in Monterey County Jail came after he was charged with a felony for throwing a rock at a fire truck, plus a parole violation, according to Sand. He was arrested then charged on May 19, 2021, and released, Monterey County Superior Court records show. David was put back in jail a few months later for failing to appear at a court hearing, and released again. He cycled in and out yet again, before finally being incarcerated on May 2, 2022, where he remained until his death.
The county jail has a history of deaths, including deaths by suicide, and is currently under a court-ordered monitoring program that was supposed to lead to reductions in incidents. The monitoring came as a result of a lawsuit filed by inmates in 2013 over jail conditions. In 2015 a settlement was reached that included the monitoring program.
After the death of Juan Carlos Chavez on April 20, 2022, Monterey County Public Defender Susan Chapman told the Weekly that the Monterey County Sheriff’s Office, which runs the jail, had made “significant efforts in improving safety and healthcare at the jail.” More work still needed to be done, she said.
Inmate Sergio Gonzalez died from Covid-19 on Sept. 24, 2021, while in custody during an outbreak of the virus. The family filed a lawsuit in September. Another man died under uncertain circumstances the month before. And another suspected death by suicide occurred in June 2021.
Days before David’s death, Moses lost his bid for the position of Monterey County Sheriff to Marina Police Chief Tina Nieto in the election on Nov. 8. Moses ran on a platform of expanding mental health services to inmates, many of whom suffer from mental and substance abuse illnesses. He told the Weekly he has collaborated with Monterey County Behavioral Health and community-based organizations to use state funds to convert the old jail into a behavioral health treatment center.
Moses also said under his leadership jail officials have made “great strides” in offering more mental health services, including the Jail-Based Competency Treatment program “so that those that have severe mental health issues can get rapid and intensive treatment without waiting for bed space” at a state hospital.
The captain said they had also begun the Medication Assisted Treatment program inside the jail “to give those that suffer from substance abuse the tools they need to overcome their addictions and transfer them to community-based care once released.
“We also just started an Early Access program to expand intensive services for those suffering from mental health issues before they even begin the court process. All these programs are being funded by sources outside of the county general fund,” he said.
In addition, Moses said the jail has become safer in the last few years, including 30 percent fewer suicide attempts.

I meant in Monterey County Jail in April
My husband, Juan Carlos Chavez passed away I'm on our way County Jail in April. His death has still not been released to the public. My husband did not commit suicide he was murdered. The jail, Joe Moses and the sheriff's department has done everything that they can do to cover up his murder and it makes me sick to think that this is our law enforcement. I'm shocked that they have even, released as much information as they have on this man's death. The new sheriff, Tina Nieto, has the full support of mine and my husband's family. I hope that the first thing she does is fire Joe Moses and everybody else working at that jail, who are ultimately responsible for these deaths. Hopefully with all new staff, these unnecessary deaths would be able to be prevented in the future. This is so sad. I invite this Man's family to contact me through Facebook. Maybe we can all work together to come up with some ideas to make sure that this never happens again.
My condolences to you and your family, Anabel. David was one of my younger brother's. As I was researching the Monterey County jail over the past week, I did read the story written about your husband, Juan Carlos. Although we did receive some details, we have many unanswered questions as to the circumstances of David's death.
After reading your message here, I felt compelled to respond. Tough time of year for families that are grieving. I hope you're surrounded by loved ones and can find some peace.
Take care.
Thank you and my condolences to yours. I apologize for just seeing this now. Is it true that now they are claiming that your brother drank water to death? That's quite different than cutting himself.
They claimed this same thing about another inmate a couple years ago. I don't believe it. ... and based on the fact that there has been more than 5 "suicides" since your brother, shouldn't the state step in at some point and do a real investigation, considering most of these people were in booking and facing no more than a few days in jail?
This is wrong. This is not negligence or suicide. Someone is murdering these people andit has to stop!
