CHICAGO (CBS) — Cook County Board President Toni Preckwinkle is responding to questions about a shooting involving a member of her security team.

The Forest Preserves Police officer fired a gun during an attempted carjacking outside Preckwinkle’s home in Hyde Park last month.

Cook County Commissioner Sean Morrison sent Preckwinkle a letter asking why no one was ever told about the incident.

Preckwinkle responded in a letter that the incident happened in the city of Chicago, not on Forest Preserves property, so it’s a Chicago Police matter, and she didn’t want to jeopardize the investigation.
