More than 350 pounds of dynamite stolen from a work site in Lancaster County, Pa., last weekend has been recovered, authorities said.
Investigators with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) on Friday recovered 320 cartridges of the explosive, weighing 352 pounds,Harrisburg’s FOX43 reported.
But it remained unclear at the time of recovery how much more of the explosives were still unaccounted for, ATF spokeswoman Charlene Hennessy told PennLive.com.
“We’re continuing to investigate and trying to determine what happened,” she told the outlet.
Agents also found 404 blasting caps, four more than the original estimate. A blasting cap is used to trigger an explosive device.
A hiker spotted the high explosives while walking the trails at River Front Park and alerted police, FOX43 reported.
ATF special agent Don Robinson told the station that the items were most likely left at the park within the last 48 hours.
Investigators conducted a full inventory check after the theft was reported last week and learned 704 pounds of dynamite and 400 blasting caps had been stolen from a locked truck trailer at the Atlantic Sunrise pipeline worksite in Marietta. Authorities at first believed the amount of dynamite to be 640 pounds.
