In an 'unprecedented' move, five alleged Aryan Brotherhood members will not have to appear at certain court hearings in person as prosecutors fear they are too dangerous. In a stipulation filed on Tuesday, Ronald Yandell, Danny Troxell, Pat Brady, Jason Corbett and William Sylvester all agreed to appear by video to all hearings where their appearance wouldn't be required or valuable to the defense. Prosecutors feared the men would escape as they said the men were found making ropes and fishing lines and asking about details about their transportation to court. The men are among two dozen alleged Aryan Brotherhood members and associates charged in connection to five prison murders, four murder plots and a large-scale drug trafficking ring within the California state prisons. U.S. District Judge Kimberly Mueller agreed that the decision was 'unprecedented,' and defense attorney's argued that the move infringes upon their clients' right to face criminal charges in person. Accused: Daniel Troxell, left, and Ronald Yandell, right, are among 16 leaders and associates of the Aryan Brotherhood gang who are awaiting trial in California Prosecutors said alleged Aryan Brotherhood inmates including Jason Corbett (left) and William Sylvester (right) may be too dangerous to leave jail even for a court appearance The defendants were charged with murder, plotting murder and running a large drug-trafficking ring within the California State Prison-Sacramento, pictured above The prosecutors added that the prisoners' dangerous behavior was evident as they continued to commit crimes while being held at Sacramento County Jail and New Folsom Prison, The Mercury News reports. According to federal prosecutors, the men were plotting to smuggle cellphones into the Sacramento County Jail and discussed 'taking out' a person who had introduced on their wives to an undercover federal agent. Court records also said that the defendants were seen 'eyeing locks,' exchanging secret messages, and that another alleged Aryan Brotherhood member, Samuel Keeton, had tampered with the lighting device in his cell. Troxell is a convicted killer serving a life sentence who spent more than 20 years in solitary confinement. Five other defendants are also convicted murderers, including Jason 'Jake' Corbett and William Sylvester who are both accused of further killings in prison. Sylvester and his cellmate, Yandell, allegedly used smuggled cell phones to organize heroin and methamphetamine in California. Yandell, serving a life sentence for a double murder, is described as one of the gang's three-member leadership commission, as is Troxell. Some of the inmates could face the death penalty if they are found guilty. Prosecutors say one murder victim was a longtime leader of a rival black gang, killed just days after he was released from decades of solitary confinement. Black Guerilla Family leader Hugo 'Yogi' Pinell, a killer with ties to the 1960s black revolutionary movement, was killed by the Aryan Brotherood in 2015, it is alleged. Pinell became infamous as a member of San Quentin Six, helping slit the throat of prison guards during a failed 1971 escape attempt that left six dead. In addition, attorney Kevin Macnamara is accused of aiding the gang by helping smuggle drugs and cellphones into prisons. Guards have alleged finding three phones, plastic wrappers and power cables concealed in the seat cushion of Macnamara's wheelchair. Despite its racist philosophy, the Aryan Brotherhood had a drug smuggling partnership with the Mexican Mafia, prosecutors claim. Authorities have been trying to bring down the Aryan Brotherhood, also known as The Brand, for decades. The gang was formed by white inmates in the mid-1960s and has a policy of 'blood in, blood out,' holding that full members must kill to gain entry.
