Fear, intimidation and no intimidation and no accountability. Those words camfrom twauditors looking into the san clara county jail after the death of an inmate. Jess wipe now, Senior Investigative reporter Stephen Stock has uncovered evidence that these problems date back years. Stephen . Stephen oncam we began investitingfter the death of inmate Michael Tyree last september. We analyzed data from the countys independent Jail Observer Program. And interviewed eight different corrections officers. They all told the same story a history of abuse and mistreatment of inmates thattook place well before tyreedied.

Stephen cthe sherf disputes th. They reported on february 20th they had many of the same allegations we uncovered. So the culture has changed tremendously since i started. These two correction officers were seen on camera. Another half dozen officers talked to us off camera. All of them pointed to a lack of trabing, short staffing and a lack of accountability at the jail date back to at haes 2010. Is there a problem with the culture . Absolutely. This officer would speak to us only if we hid his identity because he fears hell lose his job and a tenyear career if he speaks out. The actuality of what is occur nk facilities is different things. Training is different. I think trainings a huge darchs. Shawn allen serves as a correction officers. Hes filed suit against the county and the sheriff for civil Rights Violations and harassment. In the the interview he acts an employee representative at the department of corrections zuch increase your staffing increase your bed space and give people the tools to do the job. This extends wait back past michael tyrys death. The intent is to provide a neutral resource for resides, inmates. Kate jones serves as the Human Resource coordinator. They take anonymous calls from inmates, and even correction officers who want to report a problem. I got behind of the increasing calls. In 2013 jones and her team began formal live transcribing entire complaints not only from inmates butch also from their families and officers. Roughly how many calls do up get a year in. Well that roughly doubled from 2014 to 2015. Thats double the nearly 100 reports filed in 2014. We revealed every one of those formal transcripts dating back to 2013. They covered issues such as the jail environment, lack of appropriate medical care Prescription Medication and officer mistreatment of inmates. Since july 2013 there have been 22 different officer involved treatment related issues including specific allegations of official abuse. There are some things that concern me greatly of course. We caught up with sheriff smith after the auditors public live released their reports to the commission. You heard a lot about culture. What was your reaction to that . Give me a chance to really take a look at the report and everything. I heard a lot of disturbing things today. Does that start with you and your organization . The entire organization. We flup needed to be a lot of reforms. This man serves at a O Organization meant to advance the civil rights. It became this eclipsing issue that would keep coming up every week of a family saying im really concerned about my son or my loved one. Oo. We shared the Jail Observer Program. This idea that this is a new problem that had no history is it just a false narrative. I think the data here proves that come planets had been surfaced that they had been communicated. The county needs to take some serious considerations, looks into who they got running their james system. Shes not the right person to run this organization. Actually, i think shes running it into the ground. Now the sheriff dispults this and she and the count each also dispute allen as claims filed in his lawsuit. Sheriff smith did confirm to me that she and her administration knew about all this data and the complaints compiled by the Jail Observer Program dating back years. Shes said shes not sure why there has been an increase in the last few years, especially about officer treatment of inmates. She blamed budget cuts for the staffing circles and saidle she would stay tuned. Theres some serious claims there. Absolutely serious. And the fact that it goes back tore so long was never addressed.
