Phoenix, Maricopa County, AZ: Police, Sheriff, DPS Break Up Prison-Jail Gang...Two-thirds of those indicted were working from behind bars...A multi-agency investigation has resulted in the arrest or indictment of 65 gang members, most of them operating out of prisons and jails. The investigation, known as "Operation Wolf Pack," started nearly two years ago in the Maricopa County Sheriff's Office, and eventually involved Phoenix Police, the Department of Public Safety, and the County Attorney's office. Of the 65 people indicted, investigators say 38 were in the Maricopa County Jail, state prisons in Arizona or California, or the federal prison system. Charges against them include conspiring to commit violent offenses against witnesses and people cooperating with police, drug trafficking, extortion, money laundering, witness tampering, tax fraud, trafficking in stilen vehicles, and ID theft. In addition, some are accused of working to sneak cell phones, heroin, and meth into prisons and jails. Investigators say while it was one organization, members belonged to 24 different street gangs that were coooperating with each other.
