(Lodi) Columbia County authorities are asking the public’s help in their investigation into the deaths of three people over 20 years ago. The sheriff’s office and Lodi Fire Department responded to a home on Clar-Mar Drive on August 22, 1998. Sheriff Roger Brandner says despite the best efforts of neighbors and emergency responders, Cheryl Cady and her children, Cory Cole and Bria Meitner succumbed to carbon monoxide poisoning. Brandner says for 23 years, detectives have utilized every available investigative method, technology, and resources in an effort to understand what happened. Most recently, a new team of investigators has assumed responsibility for the investigation. Brandner says this new team continues to collaborate with local, state, and federal partners to leverage their collective resources to further this investigation. He says they are appealing directly to those who knew Cheryl, Cory, and Bria. The sheriff asks those who may have known them at work, in school, from activities, or in the neighborhood to come forward. Brandner says conversations you participated in, observations you made, or any knowledge you have regarding them, may be important to the investigation. He says learning more about who they were as individuals helps them develop a deeper understanding of their relationships, challenges, and goals for the future. Brandner adds even if you think the information you have is not important or relevant to what occurred, they encourage you to come forward and let them make that determination. Contact Detective Captain Jason Kocovsky, if you have any information regarding this investigation at 608-742-4166 ext. 3302.
