Few signs that Doe probe will net more suspects
Walker has continually said he's not target of investigation
When a former aide to Gov. Scott Walker is sentenced next week, that will bring to a close the second of six cases that grew out of a long-running investigation into Walker's office when he served as the Milwaukee County executive.
Details of the probe are secret, so everyone from investigators to those being investigated are prohibited from discussing details. So it's not clear how close the so-called John Doe probe is to wrapping up.
But there have been few indications that additional suspects will be named. Online court records that are updated whenever new witnesses are granted immunity in exchange for their testimony haven't been modified in almost six months.
Walker has continually said he's not a target of the investigation, and has not been charged.
