The head of the Missouri State Highway Patrol says his agency provided a list of 163,000 Missouri residents with concealed gun permits to federal authorities. But he says federal investigators never used the information.

Patrol Superintendent Col. Ron Replogle testified Thursday before a Senate committee that has raised concerns about a database on driver’s license applicants kept by the Missouri Department of Revenue.

Replogle says the patrol twice got a list of concealed gun permit holders from the Revenue Department and shared it with a fraud investigator at the federal Social Security Administration. But Replogle says the federal investigator was unable to read the information stored on the discs and ultimately destroyed them.

Replogle told senators the patrol should not have released the whole list.
