Investigators from the Tombstone Marshall’s Office found a pipe bomb overnight while responding to a call about a man who died in his home.

After the bomb was found, Tombstone officials requested the assistance of Cochise County Sheriff's Office.

The Tombstone Marshall’s Office “advised that there appeared to be a pipe bomb inside of the home, and the Sheriff's Office bomb tech was dispatched to the scene along with two techs from the Arizona Department of Public Safety” bomb squad, Carol Capas, spokeswoman for the sheriff’s office, said in a news release.

In the home and other buildings on the property marshal’s investigators found a large pipe bomb; approximately five pounds of ammonium nitrate; electric and non-electric explosive initiators; KinePac, a binary high explosive; and a large amount of time fuse.

All items were rendered safe or secured by utilizing explosive materials at the Tombstone airport, Capas said.

The investigation by the Tombstone Marshals Office is ongoing. The cause of death for the man in the home is undetermined. An autopsy is being performed by the Pima County Medical Examiner.
