DNA Technology Brings Decades-Late Justice in Fresno Sexual Assault Cases

A Fresno man will spend decades in prison after pleading guilty to sexually assaulting children and adults over nearly a decade — crimes that went unsolved until advances in DNA technology, including genetic genealogy, finally identified him.

Cesar Flores, 56, was sentenced July 21 by Judge Jim Kelley to 30 years to life, plus a consecutive 16 years, after pleading guilty June 18 to two counts of forcible rape and two counts of committing a forcible lewd act upon a child. The crimes occurred between 2014 and 2021, though earlier reporting cited charges dating back to 1997.

Flores was arrested July 1, 2025, after investigators used investigative genetic genealogy — a tool that matches crime-scene DNA to public genetic databases — to link him to multiple previously unsolved sexual assault cases. He’d been charged with 22 crimes against seven victims; the other charges were dropped as part of the plea deal to spare victims from testifying, according to the DA’s office.

“For years, they carried the weight of these horrific crimes while the person responsible remained unidentified,” Fresno County District Attorney Lisa Smittcamp said in a statement. “Today, they know the man responsible has finally been held accountable.”

As part of his plea, Flores admitted the victims were particularly vulnerable and that his violent conduct shows he poses a serious danger to society. He’ll register as a sex offender for life, and the court issued protective orders for the victims.

The case was prosecuted by Senior Deputy District Attorneys Adam Christopherson and David Devencenzi, with investigative work by Fresno Police Department detectives Steve Taylor, Pete Ressler, and Phu Nguyen, along with others.

The Breakdown

• Flores pleaded guilty to four counts: two forcible rapes and two forcible lewd acts on a child, spanning 2014–2021.
• DNA technology, specifically investigative genetic genealogy, linked Flores to the crimes after years of the cases being unsolved.
• He was originally charged with 22 crimes against seven victims; 18 charges were dropped under the plea agreement to avoid forcing victims to testify.
• His sentence: 30 years to life (indeterminate), plus 16 years (determinate), for a minimum of 20 years before elderly-parole eligibility. Eligibility doesn’t guarantee release — the parole board will evaluate his behavior, rehabilitation, and danger to the public.

What This Means for You

This case is a window into how the Fresno County District Attorney’s Office uses evolving forensic tools and how it balances prosecution against protecting victims from courtroom trauma. Smittcamp’s statement frames this as a commitment to cold cases “no matter how much time has passed,” a policy choice about resource allocation and prosecutorial priorities.

This case highlights the importance of delayed federal grant funding needed by the City of Fresno to test 400 “rape kits.” Currently, $2 million in grants from the federal government has been withheld based on the city’s objection to complying with immigration policies. Several other California and Oregon counties have joined a lawsuit to block the requirements they say are unlawful. United States District Judge William Orrick has issued a preliminary injunction halting the conditions.

What to Watch

Flores will be eligible for an elderly-parole hearing after serving his minimum term, though eligibility is not release. The DA’s office says it will “continue to advocate on behalf of the victims” during any future parole process — a statement worth holding them to. Will the office treat this as a one-time press release, or will it actually show up when the parole board convenes? Victims of violent crimes are often promised long-term support that quietly evaporates once the case leaves the news cycle. Whether this office follows through when the cameras are gone is the real test of the commitment being claimed here.
