By the way, for those that are watching for activity, keep an eye on the Maricopa County Jail. You need first name, last name, and date of birth to search which you can get from some convenient sources like copies of Clark County, NV marriage licenses, for example. People arrested in Maricopa on out of state warrants or federal warrants will not show up in criminal court case searches on the Maricopa County court web site.
