“My 15-year old nephew Steven was shot and killed by the Chicago Police Department,” Terinica Thomas-Level, 28, said, weeping and shaking visibly as she stood before the news media. “I need the attention of Mayor Emanuel. I need to see evidence. Body cams. They need to release the video. My nephew would never commit suicide ever. … If he (Emanuel) even had the smallest compassion for our family, he’d get those videotapes released.”
