Officials are looking for information about a discovery of explosives in Pine, Arizona last year.
A construction crew was clearing land in a rural area of Pine on Wednesday, Oct. 25, when they unearthed a collection of military explosives.
Eighty blocks of military C4 explosives, nine Claymore antipersonnel mines with firing devices, and one roll of military detonating cord were found inside plastic cylinders buried underground.
A spokesperson for Alcohol, Tobacco, Firearms and Explosives says they're working to find the person who stole or buried them.
"I think it's safe to characterize this as one of the larger recoveries we've seen," ATF agent John Durastani said.
Investigators believe the explosives were in the ground for approximately 20 years before they were found.
"We have no information to suggest that anything nefarious was going to occur or that these were being stored for a future act," Durastani said.
Anyone with information is asked to contact the Bureau of Alcohol, Tobacco, Firearms and Explosives hotline at 1-888-283-8477 or send an email to ATFTips@atf.gov.
A $10,000 reward is being offered for information leading to an arrest and conviction in this case.
