The Arizona Attorney General's Office has turned over the criminal investigations of law enforcement officials in Maricopa County to federal prosecutors.
The Arizona Republic learned that after consulting with the U.S. Attorney's Office in Phoenix, state prosecutors found that four investigations into county officials overlapped with a federal abuse-of-power probe.
The four investigations involve current and former employees of the Maricopa County sheriff's and county attorney's offices. At least three stem from the years-long conflicts among county supervisors, judges and rank-and-file employees.
The probes are looking at campaign funding, jail spending, a land deal and the filing of criminal charges against a county supervisor, among other things.
A federal grand jury has been investigating Maricopa County Sheriff Joe Arpaio and other officials on abuse-of-power allegations since at least January 2010.
