MART -- Police are finding new details in the case of false 911 calls in Mart that lead to the caller threatening to kill the Police Chief, David Monthley, and his family.
Now Facebook posts are threatening other officers and their families.
Chief Monthley says it started with the caller making false reports of serious car accidents and fights, but turned into threats of killing the chief and blowing up his home.
After more than 20 harassing calls, the Texas Rangers have stepped in to find the caller.
Police say they do have leads and will seek charges on all threats.
