Shortly after the October 15 presidential debate, in which McCain repeatedly referred to “Joe the Plumber,” Wurzelbacher’s Ohio state records were illegally accessed.

The criminal investigation conducted by the Ohio Department of Highway Patrol is now focused on an outside computer contractor who did work four years ago for the Ohio Department of Insurance. The as-yet unnamed contractor is thought to have used an old computer test account to access the state databases.

The ongoing investigation is also looking into a search of the Ohio Department of Job and Family Services records that was approved by the department’s director, Helen Jones-Kelly. Jones-Kelly said she approved the records check to determine whether Wurzelbacher was behind on child support payments.

Also part of the investigation are the three searches of Wurzelbacher’s Ohio Bureau of Motor Vehicles records that were made from within the Toledo Police Department.

Earlier this year it was discovered that private contractors repeatedly accessed passport records of Sens. Obama, Clinton and McCain.
