CLAYTON, Mo. (AP) — An FBI investigation into fraud at the St. Louis County Health Department is complete, but elected leaders say they don't know the findings.

County officials sought federal help to unravel a $3.4 million computer fraud scheme created by a county health manager before he committed suicide. But the St. Louis Post-Dispatch ( ) reports that only County Executive Charlie Dooley and a handful of his advisers know the details about Ed Mueth's embezzlement scheme or the FBI audit, which was completed in January.

Meuth used an alias and bogus invoices to collect millions during a six-year scheme to sell and lease laptop computers to the county.

A Dooley statement says the FBI asked that the audit details not be disclosed to St. Louis County Council members.
