Woman convicted of killing Chicago police officer

CHICAGO – A woman has been convicted of killing a Chicago police officer with his own weapon following an altercation on a Chicago Transit Authority bus.

The Chicago Sun Times reports (http://bit.ly/1cnkrf3) a jury on Wednesday found 50-year-old Robin Johnson guilty of murder, disarming a police officer and aggravated discharge of a firearm for the 2008 incident.

Prosecutors said the shooting occurred after Francis responded to a report of an altercation on a bus. When the 60-year-old officer arrived, Johnson was outside pacing, stomping her feet and talking to herself. They said Johnson then grabbed Francis' gun and shot him.

Assistant Public Defender Kulmeet Galhotra says Johnson was "confused, distressed and in need of help" when Francis approached her.

Johnson, who's from Chicago's West Side, faces life in prison when she's sentenced.
