JACKSON, Wyo. \u2013 Investigators say they are not ready to close the case on a structure fire at Caf\u00e9 Genevieve last summer until a \u201ckey witness\u201d agrees to come forward.\r\n\r\nThe fire discovered on July 2, 2019, at 2:54 a.m. was quickly extinguished by Jackson Hole Fire\/EMS responders but not before extensive damage was done to the building. Caf\u00e9 Genevieve has remain closed for business ever since.\r\n\r\nA police spokesman announced today that a joint investigation into the cause of the fire conducted by members of the Jackson Police Department, JH Fire Department, Wyoming State Fire Marshall\u2019s office, and the Division of Criminal Investigation (DCI) has turned up no conclusive evidence as to how the fire started. DCI Arson Investigations Team and the State Fire Marshall are declaring the cause \u201cundetermined\u201d at this point in the investigative process, meaning they cannot determine if the fire was human-caused or otherwise, based upon the physical evidence alone.\r\n\r\nNumerous witnesses were interviewed but one critical eyewitness has yet to cooperate with investigators. This case will remain an active and open investigation until such time as the last remaining witness can be interviewed to determine if this individual can provide critical information in the case or not. Jackson Police Department spokesperson Sgt. Roger Schultz would not identify that person.\r\n\r\n\u201cThe next steps are we wait, and the case remains open indefinitely unless or until we interview this key witness,\u201d Schultz said. \u201cWe can\u2019t force them to come forward.\u201d\r\n\r\nAnyone with information related to the fire is asked to contact Detective Rob Andazola of the Jackson Police Department at (307) 733-1430.\u00a0 Anonymous tips can also be left at Jackson Hole Crime Stoppers at (307) 733-5148.
