Since no criminal charges have been filed in the disappearance of Gail Palmgren, attorneys for Matthew Palmgren have agreed search the family's property, provided an attorney is present at the time of the search.
"If there was credible evidence to show us that we would focus on criminal activity here, perhaps we would have moved a quicker on some of these things," said Hamilton County Sheriff Jim Hammond.
In an interview Wednesday, Hammond told Channel 3 this is still a missing persons case.
"I've seen cases strange enough where you would just swear somebody was dead to foul play and they do turn up, even years later," said Hammond, "so you can't discount that."
Hammond says it's possible investigators will conduct an aerial search of Signal Mountain once the weather changes and the leaves fall, giving the area more visibility.
"Probably the best thing that can help us is if anyone happens to remember that unique Jeep with the insignia on the back, and can remember something that would assist us bring closure to this case," said Hammond.
