Four members of a militia group associated with the boogaloo movement have been indicted for allegedly trying to obstruct justice and destroy evidence related to the murder of a federal officer in Oakland.

The suspects-- identified as 29-year-old Jessie Alexander Rush of Turlock, 33-year-old Robert Jesus Blancas, 23-year-old Simon Sage Ybarra of Los Gatos and 21-year-old Kenny Matthew Miksch-- were indicted by a grand jury. they are believed to be involved in a militia group identified with the boogaloo movement called the "Grizzly Scouts."

The case is related to the May 29, 2020 shooting at a federal building in Oakland and one of the suspects in the case, Steven Carrillo. Carrillo is also charged with the murder of Sgt. Damon Gutzwiller with the Santa Cruz County Sheriff's Office.

Group Contact

According to the indictment released by the U.S. Attorney's Office, Rush, Blancas, Ybarra, Miksch and Carrillo were all members of the Grizzly Scout militia group, which was reportedly founded by Rush in March or April 2020. It is believed that the group used WhatsApp and a Facebook group to communicate as early as April 4 through June 6, 2020. They also sometimes met for gun training and discussed violence against law enforcement over messaging applications.


Steven Carrillo is one of two people charged for the murder of Protective Security Officer Pat Underwood in Oakland.

According to the U.S. Attorney's Office, Carrillo was the passenger in a white van driven by Robert Alvin Justus Jr. when he opened fire on two officers, injuring one of them and killing Underwood. He is charged with murder and attempted murder in connection to that shooting.

By at least June 1 and through June 6, the group reportedly discussed tactics for killing law enforcement in a WhatsApp group.

On June 6 when Gutzwiller was killed in what law enforcement called an ambush in Ben Lomond. Minutes before the shooting, the U.S. Attorney's Office said Carrillo messaged the group saying that he was preparing for a shoot-out with law enforcement and asked Rush, Blancas, Ybarra and Miksch for help. He later messaged the group to say he "offed a fed."

At that point, investigators said Rush told Carrillo over the app to "factory reset" his phone to delete evidence, and at some point on or before Aug. 6, investigators said the four men deleted records of the group messages from their phones.

Within an hour of the Ben Lomond shooting, investigators said Blancas deleted 20 files related to the Grizzly Scouts from a Dropbox account. Some of the content of the files appeared to include the rank structure, confidentiality agreements, a liability release waiver, descriptions of uniforms and scorecards related to member training.

Within a few hours of the shooting, the U.S. Attorney's Office said the members began to communicate using alternative means, and several enabled an option for disappearing messages.

Investigators say that the group members confirmed to each other several times that they destroyed evidence related to the Grizzly Scouts.


Rush, Blancas, Ybarra and Miksch are charged with conspiring to alter, destroy or conceal records and documents related to the Grizzly Scouts militia group to prevent the use in official investigations related to the murder of Pat Underwood and attempted murder of another officer. They are also charged with specifically altering, destroying or concealing messages from the WhatsApp group to prevent their use in official proceedings.

Additionally, Rush is charged with trying to destroy evidence on his phone related to the murder, and Blancas is charged with destroying files about the Grizzly Scouts on Dropbox.

Ben Lomond "Ambush"

Early in the afternoon on June 6, 2020, the Santa Cruz County Sheriff's Office got a call about a suspicious van containing guns and bomb-making materials parked near Jamison Creek, and when deputies got to the area, they saw it leaving and followed it to a home on Waldenberg.

During the investigation, the Sheriff's Office said the deputies who responded were ambushed with gunfire and explosive devices.

Gutzwiller was shot and died at the hospital. Another deputy was injured and then hit by a vehicle as Carrillo tried to leave the area, according to investigators.

After that, law enforcement got reports of a nearby carjacking, and a CHP officer was shot in the hand while responding. Carrillo was detained nearby by a community member and left evidence of his association with the boogaloo movement, according to the U.S. Attorney's Office.
