Catrell Churchman was 20 when he was killed on the evening of July 12, 2012. Earlier that year he had traveled to Jefferson City as a student from Shearwater, a school for dropouts, to testify in favor of a bill expanding charter schools — testimony described as powerful enough to move a state senator to tears.

His life ended while standing in front of a cousin’s home in St. Louis, where he was gunned down. No suspects have been named and no arrests announced; information about the official investigation has not been made public, and the case remained unsolved as of September 2012.

If anyone knew Catrell, was with him that evening, or has information about the shooting, please come forward.
