Phone records obtained by investigators showed that the deputy's brother-in-law called the inmate's sister, according to the district attorney's memo. The sister told sheriff's officials she gave heroin, cash and the shoes to a man who described himself as the brother of the deputy.
Giron's brother-in-law denied receiving drugs from the inmate's sister but also "stated he was not a 'snitch,' " the district attorney's memo says. The deputy adamantly denied providing the inmate with narcotics and told investigators he did not know why a childhood friend would accuse him of a crime.
Two more inmates reported seeing Giron provide the drugs. But the district attorney's memo, written by Deputy Dist. Atty. Paul Nunez, expressed concern about their credibility.
One of the inmates, Nunez wrote, was a convicted murderer who had provided "a large amount of useful information to detectives on a number of deputies" but had "failed to inform investigators of other deputies who were actively bringing in narcotics for him."
In declining to file charge against Giron, Nunez wrote that investigators never recovered physical evidence — drugs, shoes or cash — and described the deputy's accusers as criminals whom jurors would conclude were not credible.
Giron's attorney, Richard A. Shinee, described the deputy as well-respected and accused the inmates of making false accusations. "It's all smoke and mirrors created by a couple of con artists who were in jail and trying to buy off more time," he said.
Authorities have successfully used Giron's childhood friend to identify a corrupt deputy in the past and said he is involved in ongoing investigations. Law enforcement officials asked The Times not to name him because of concerns for his safety.
Giron has been placed on leave by the Sheriff's Department. A department source said Giron's case would be referred to the U.S. attorney's office next week for possible federal prosecution.
