Sixteen members and associates of a prison-based gang have been charged after a long-running investigation into drug trafficking and murders inside and outside of California’s prisons.
Assistant Attorney General Brian A. Benczkowski of the Justice Department’s Criminal Division, U.S. Attorney McGregor W. Scott for the Eastern District of California and Special Agent in Charge Chris Nielsen of the U.S. Drug Enforcement Administration (DEA) made the announcement.
According to a criminal complaint unsealed today, nine defendants have been arrested on federal racketeering and other charges for extensive, organized criminal activity from within California’s most secure prisons. The allegations include murders, drug trafficking and other violent crimes. The complaint charges California State Prison inmates Ronald Yandell, 56; Daniel “Danny” Troxell, 66; William Sylvester, 51; Travis Burhop, 46; Brant Daniel, 44; Donald Mazza, 48, Pat Brady, 48; Michael Torres, 55; and Jason Corbett, 47. At the outset of this investigation, Yandell, Troxell, Sylvester, Burhop, Torres and Corbett were all serving life sentences for murder.
Five other individuals were also arrested as part of the investigation: Samuel Keeton, 40, of Menifee; Jeanna Quesenberry, 52, of Sacramento; Kevin MacNamara, 39, of La Palma; Kristen Demar, 44, of Citrus Heights; and Justin Petty, 37, of Los Angeles. Warrants have been issued for the arrests of Kathleen Nolan 64, of Calimesa, and Matthew Hall, 50, of Manhattan Beach.
According to court documents, between 2011 and 2016, Aryan Brotherhood (AB) members and associates engaged in racketeering activity, committing multiple acts involving murder and drug trafficking offenses. Yandell and Sylvester oversaw a significant heroin and methamphetamine trafficking operation from their shared cell. They used smuggled-in cellphones to direct their drug trafficking activity from their cell to the streets of Sacramento and other California cities. Using a contraband cellphone, Yandell and Sylvester communicated with AB members and associates to direct drug trafficking activities, membership in the AB, order murders, and oversee other criminal activities.
The complaint alleges that the AB members murdered five other inmates as part of their gang activities and conspired to murder several others. The complaint alleges that, on Oct. 7, 2011, Sylvester murdered an inmate at Folsom State Prison and, on Aug. 12, 2015, AB associates carried out an order to murder a rival prison gang member at Folsom State Prison.
In addition, the complaint alleges that on Oct. 15, 2016, on Corbett’s order an AB associate murdered an inmate at High Desert State Prison in Susanville, AB member Daniel killed an inmate at Salinas Valley prison on Oct. 29, 2016, and that AB members Corbett and Brady murdered an inmate on July 20, 2018, at High Desert State Prison as part of their role in the gang. The complaint further describes multiple other murder plots.
The complaint details the drug trafficking activities of the AB. Members and associates oversaw an extensive drug-trafficking network that operated on the streets of Sacramento, Southern California, Missouri, Las Vegas and elsewhere. On Aug. 11, 2016, MacNamara, a lawyer, and Demar, posing as a paralegal, visited Sylvester in Folsom State Prison in order to smuggle methamphetamine, cellphones and tobacco. When the contraband was discovered, Sylvester, using a cellphone, advised Demar to blame their contraband smuggling on the AB in order to get out of trouble.
According to the complaint, Petty sent heroin, methamphetamine, cellphones and other items concealed in food packages to AB members at Folsom State Prison and High Desert State Prison. In addition, the investigation uncovered a drug trafficking partnership between AB members Yandell and Burhop with Torres a Mexican Mafia member.
