Threats to people and places and the use of a bomb were made to three different sheriff agencies in the west Tuesday night.
Reports show threatening phone calls were made to Teton County Sheriff’s Office, Natrona County Sheriff’s Office, and Garfield County Sheriff’s Office in Colorado.
Reports also show the threatening phone calls were also received by citizens and businesses in the Casper area and Teton County.
Teton County Sheriff Deputies told News 13 this was not the first time bomb threats have been made to Jackson places this year.
Teton County has issued an arrest warrant for 33-year-old Kreighton Kilgore, a former Jackson resident who they believe is a transient and has left the state, but was responsible for a similar bomb hoax in January.
Teton County Deputies said the Tuesday night calls were similar to the past calls and have reason to believe it was again, Kreighton.
Those threats have resulted in arrest warrants for Kilgore for terroristic threats.
However, the Natrona County Sheriff's Office is pursuing their own investigation into the threats.
Thursday morning new details were released in Natrona County, showing the caller threatened the NC Sheriff's Office with explosives from a residence along the 1500 block of Walnut Street.
The caller claimed he was bringing explosives to the sheriff's office.
Since the Tuesday incident, the Federal Bureau of Investigations has been called in to work in conjunction with agencies.
Both agencies take these threats seriously and are actively investigating.
