Authorities found numerous homemade explosives inside the home on Saturday. Gathercole is in jail in Nebraska and is accused of shooting at a Kansas state trooper with an AK-47 rifle a week ago.

According to the transcript, Gathercole tells his mother to get all the guns out of the house. She agrees, then reminds him that the call is being recorded.

Federal agents say a weekend search of a south-central Montana residence that turned up homemade bombs was connected to a bank robbery investigation.

FBI Los Angeles spokeswoman Laura Eimiller says numerous agencies were investigating whether evidence found in the search in Roundup, Montana, was connected to a series of bank robberies in California, Washington state, Idaho and Nebraska.

In 2012 and 2014, a man the FBI called "the AK-47 bandit" robbed several banks. The robber shot and wounded a police officer in Chino, California.

Officials with the Musselshell County sheriff's office in Montana say the weekend search was linked to 39-year-old Richard Gathercole, who was arrested last week in Nebraska. He was wanted after someone fired shots at a Kansas trooper. The trooper wasn't injured.

Officials did not say how Gathercole was connected to the residence where the bombs were found.
