Information submitted through the tipline may qualify for a reward of up to $5,000 if it leads to an arrest and prosecution.
“Behind every cold case is a family still waiting for answers. We owe it to this victim and their loved ones to pursue every lead, which is why we’re asking for the public’s help,” said Adams County Sheriff Gene Claps. “We want the public to know that no piece of information is too small and could be what we need to help solve this case.”
