After a postal worker in Chicago was shot and critically injured, the US Postal Inspection Service offered a $50,000 reward for information. The 24-year-old female letter carrier was “shot multiple times while working” Thursday on the South Side around noon, the Chicago Police Department said in an incident release. It seems she was not targeted, police said. “The victim has gunshot wounds to the back of both legs, buttocks area, stomach and the back of her head,” according to the release.
