OKLAHOMA CITY — A 40-year-old Seminole County man was arrested on accusations that he attached an improvised explosive device to a natural gas pipeline in eastern Oklahoma, the FBI said.
The FBI identified the suspect as Daniel Wells Herriman of Konowa and said Herriman provided a statement to investigators on Sunday in which he acknowledges manufacturing and placing the device on a pipeline near Okemah in central Oklahoma. The device, which was described as a 1-foot-by-1-foot pipe bomb, did not go off and there was no damage.
Herriman was arrested on federal charges of attempting to destroy property used in interstate or foreign commerce. He is set to appear before district court on Tuesday at 10 a.m., according to court filings.
A complaint filed in U.S. District Court in Muskogee says the IED was discovered attached to a gas pipeline on Wednesday at the Enerfin Resources gas pipeline substation near the intersection of Oklahoma Highway 27 and a county road near Okemah in Okfuskee County.
The IED was discovered by two Enerfin Resources employees who contacted the Okfuskee County Sheriff’s Office, the complaint says. A sheriff’s deputy “concluded that the item appeared to be a bomb” and worked with the Oklahoma Highway Patrol to close roads in the area, it says. The highway patrol’s bomb squad later removed and disarmed the device.
The complaint states that on Wednesday night, Herriman called the Seminole County Sheriff’s Office’s 911 operator stating “I set the bomb under the pipeline in Okemah” and offering to turn himself in.
The complaint says Herriman “subsequently confessed to manufacturing and placing the IED.” He told investigators that he placed the IED on the pipeline on Sunday and had set the timer on the device for 2 a.m., the complaint says. However, it does not provide a possible motive.
“There hasn’t been an established motive,” said FBI spokesman Clay Simmonds in Oklahoma City. Simmonds said there is no evidence that Herriman is tied to an organized terrorist group or environmental activists. Simmonds said Herriman is also not a current or former Enerfin Resources employee.
Simmonds said authorities know of no previous arrests of Herriman.
Herriman told investigators he manufactured the device at his residence and that the components used to construct it were still located there, including plastic pipes, what appeared to investigators to be black powder, a propane tank and batteries and wiring, the complaint says.
It says a search of Herriman’s residence found items similar to the IED’s components. Simmonds said the IED will be further examined and tested by FBI technicians.
Simmonds said an initial court appearance for Herriman is scheduled on Monday in federal court in Muskogee. He said Herriman faces at least five years and up to 20 years in prison if convicted. Online federal court records did not indicate whether Herriman was represented by an attorney.
The Enerfin Resources pipeline is operated by Enogex, a subsidiary of Oklahoma Gas and Electric Co. OG&E spokesman Brian Alford has said the company had not received any threats.
