The individual known as "Fernando" was said to have traveled to Puerto Rico following the murder, but his current whereabouts remain unknown, said George McDade, chairman of Cook County Crime Stoppers. Ron Clewer, Kevin Clewer's brother, said police have seen significant progress in the case over the past two years. "We're able to hopefully uncover some clues, some leads, some tips that could connect some of the dots," he said at a news conference alongside Cook County Crime Stoppers and other family members. We're really looking for...those magic tidbits of information that help bring together the various components." "Fernando" was described as a Hispanic man about 25, about 5-foot-7 with a slim, athletic build who spoke with a Hispanic or European Spanish accent, police said.
