CAPE GIRARDEAU COUNTY, MO (KFVS) - On the ground and in the air, authorities in Cape Girardeau County bring out more resources to search for Jacque Waller. The mother of triplets vanished more than three weeks ago.
"Everyday as new leads come in it's important for us to keep going with it," said Jackson Chief of Police, James Humphreys.
Chief Humphreys says every clue is valuable in the search for Jacque. They're using the Scott County K9 Search Unit to help them scour new locations.
"This morning is perfect because there's just enough moisture they can detect scents a long way off," said Marshia Morton with the K9 Unit. "One dog can do the work of 20 men on the ground. These dogs are amazing."
At the same time, the Missouri Highway Patrol helicopter took to the skies.
"We're having them fly low and search again along the interstate," said Chief Humphreys.
Now, Chief Humphreys says local and federal authorities are putting pressure on crime labs to put a rush on testing evidence he feels could bring new leads.
Meanwhile, he's asking anyone with information about Jacque and the people around her past and present to come forward.
"If you think it might be important and it involved Jacque we want to hear about it," said Humphreys.
Clay Waller, Jacque's estranged husband, is a person of interest in the case. He is not a suspect. He spoke with Heartland News briefly on the phone Monday. He tells says he is praying for his wife's safe return, and otherwise has no comment.
