Jail assault on Black inmate leads to white supremacist gang finding in Stanislaus

A dispute over who was next in line to use a jail tablet escalated into a six-on-one attack on a Black inmate and helped Stanislaus County prosecutors accomplish something that took more than five years of investigative work: locally establishing the Peckerwoods as a criminal street gang under California law.

Four inmates — Joshua Clint Keys, Matthew Jess Garza Limper, Benjamin Christopher Sorensen and Leslie Aaron Parson Jr. — have pleaded to all charges, gang enhancements and allegations stemming from the June 3 assault at the Stanislaus County Public Safety Center, according to court documents.

Each entered an open plea, meaning there was no negotiated deal with prosecutors, according to deputy district attorney Patrick Hogan. The defendants admitted to felony charges of assault by means of force likely to produce great bodily injury and participation in a criminal street gang. They also admitted to an enhancement alleging the assault was committed for the benefit of, at the direction of, or in association with, the Peckerwoods.

Keys, whom prosecutors identified as the leader who directed the attack, has been sentenced to six years in state prison: three years for the assault and another three years for the gang enhancement. Hogan said the conviction constitutes a serious strike under California law.

The other three defendants await sentencing.

The District Attorney’s Office says the case marks the first time the Peckerwoods have been established as a criminal street gang in Stanislaus County under California’s Street Terrorism Enforcement and Prevention Act, commonly known as the STEP Act.

For years, Hogan said, authorities knew Peckerwoods operated inside the county jail. Proving that the group met California’s legal definition of a criminal street gang was considerably more difficult.

“The Peckerwoods are a gang which in our county functions only in the Public Safety Center,” Hogan told The Bee.

Unlike Norteño or Sureño gangs with established activity both in custody and on the streets, Hogan said there is no corresponding Peckerwood street organization in Stanislaus County. Instead, white inmates from different backgrounds can come together under the Peckerwood identity while incarcerated.

Those inmates can include people affiliated outside custody with motorcycle gangs, Nazi Low Riders or the Aryan Brotherhood, Hogan said, as well as white inmates with no formal gang affiliation before entering jail.

That fluid structure made documenting the group as an ongoing criminal organization especially challenging.

Assault allegedly started over jail tablet

Hogan said the June attack began after a Black inmate was accused of cutting in front of a Peckerwood member waiting to use a jail tablet, which inmates can use for services including phone calls and videos.

What appeared to be a minor dispute quickly took on a gang dimension, he said.

The Peckerwoods decided as a group that they would retaliate, according to Hogan. Six inmates participated in the ensuing assault.

“Something as small as someone being cut in line can result in a gang assault,” Hogan said.

The group attacked the inmate inside a dorm-style sleeping area that was partially obscured from jail surveillance cameras, Hogan said. Investigators believe the attackers knew the location would make the assault more difficult to capture on video.

The victim suffered lacerations but no broken bones, Hogan said. Jail officials later removed him from the housing unit because authorities determined it was no longer safe for him to remain there.

Two of the six alleged participants eventually became prosecution witnesses. Hogan declined to identify them.

Investigators were nevertheless able to establish who participated and, prosecutors contend, that Keys was the ranking member who directed the assault.

The criminal information filed against the four defendants separately alleges that Keys induced others to participate or occupied a position of leadership or dominance in commission of the crime.

At the time of the assault, Keys was serving a local jail sentence, not a state-prison term, Hogan said. He had previously served time in state prison and was on post-release community supervision before committing another offense.

Five years building a gang case

California law requires prosecutors seeking gang allegations to establish specific elements showing an organization qualifies as a criminal street gang and has engaged in a required pattern of criminal activity.

That presented an unusual problem with the Peckerwoods, Hogan said.

Because the local group operates almost entirely behind jail walls, investigators could not rely on the type of street crimes, police contacts and publicly visible gang activity that help build cases against more traditional street gangs.

The District Attorney’s Office and Stanislaus County Sheriff’s Office instead spent a little more than five years developing intelligence about Peckerwood activity inside the jail, Hogan said.

A crucial part of the effort was identifying earlier crimes that could be used to establish the required pattern of gang activity.

Hogan said investigators ultimately identified two prior offenses involving Peckerwood members that prosecutors could use as predicate offenses in the June assault case.

Distinguishing gang violence from ordinary inmate fights was another challenge.

Sometimes, Hogan said, two inmates fight because of a personal dispute. Other attacks are planned, ordered and carried out because of a gang. “You have to be able to separate those two things out,” he said.

Prosecutors concluded the June assault fell squarely into the latter category.

Hogan said prosecutors made no offers in the case. An open plea allows a defendant to admit all charges and allegations without reaching an agreement with prosecutors, leaving sentencing to the judge. Hogan said that option was available because his office was unwilling to negotiate away charges in a gang-related custodial assault.

That reflects a broader policy toward violence committed inside the county jail, he said.

Prosecutors and the Sheriff’s Office became concerned that inmates believed assaults committed while already in custody would bring few additional consequences — either because victims would refuse to cooperate or because new charges might later be folded into a broader plea resolution.

Hogan said prosecutors decided that when they could prove a jail assault, they would pursue it rather than trade it away.

That is particularly important in gang cases, he said, because failing to address organized violence can allow groups to exert increasing control over other inmates.

What is a Peckerwood?

Outside the legal system, defining the Peckerwoods is more complicated than simply describing them as a single statewide gang.

Peter Simi, a sociology professor at Chapman University who studies white supremacist extremism and violent groups, said the modern prison use of the term became prominent during the 1960s and ‘70s, although the word and its racial connotations have a much longer history.

In correctional settings, “Peckerwood” — often shortened to “wood” — can describe a broader identity among white inmates without necessarily signifying membership in a particular gang.

“It doesn’t necessarily reference a specific group designation,” Simi said.

A white inmate described as a “solid wood,” for example, might be someone regarded as willing to stand with other white prisoners during racial conflicts and abide by the racial boundaries of prison culture, he said.

But specific gangs can also form under the Peckerwood name.

Simi pointed to the San Fernando Valley Peckerwoods in Southern California as an example of a more defined organization that developed a street presence.

That distinction means two people identifying as Peckerwoods in different institutions are not necessarily members of the same centralized organization.

Simi said that is consistent with Hogan’s description of the Stanislaus County jail, where white inmates with different outside affiliations can come together under a common identity once incarcerated.

Organization varies significantly from one group or institution to another, he said. “Predominantly, I would say, they have less organization and not a super-formal hierarchy.”

The racial component, however, is fundamental. It “is certainly baked into the cake,” Simi said.

That does not necessarily mean every inmate identifying as a Peckerwood adheres to a formal neo-Nazi ideology, he said. But the identity exists within correctional environments where strict racial boundaries can be maintained and enforced by inmates themselves.

Simi said the history of those divisions in California extends back decades. Major prison gangs organized heavily along racial and ethnic lines during the mid-20th century, including the Mexican Mafia, Aryan Brotherhood and Black Guerrilla Family.

Even after formal racial segregation in prisons ended, inmates continued to enforce many of those divisions themselves, he said.

Simi said groups such as the Peckerwoods can be particularly difficult to characterize because a shared identity does not automatically make a collection of inmates one formally organized gang.

What the case changes

Hogan said establishing the Peckerwoods as a criminal street gang gives prosecutors a foundation to pursue gang enhancements in future cases when they believe they can prove a crime was connected to the organization.

That does not mean every offense involving someone identified as a Peckerwood will automatically result in a gang allegation.

But Hogan said the June prosecution removes a major hurdle investigators spent years working to overcome.

Future qualifying cases could involve violent assaults, drug trafficking or witness intimidation inside the jail, he said.

For authorities, Hogan said, the larger objective is deterrence. “We very much do not want gangs to believe that they can operate with impunity in the jail,” he said.

The District Attorney’s Office credited the Sheriff’s Office’s Major Crimes Unit and Custodial Investigative Unit with working alongside prosecutors to develop the case.
