A Michigan man accused of planting pipe bombs outside AT&T and Verizon stores and leaving threatening letters at area cell towers was angry over “all of the immoral content, including pornography, on phones and cable television,” according to a criminal complaint filed Tuesday in Detroit federal court.

John Douglas Allen, 75, is facing charges of extortion and attempted damage or destruction of buildings used in interstate commerce, the filing states. He was arrested Monday night, Justice Department spokeswoman Breane Warner confirmed to The Daily Beast.

“Our office will not be offering any comment besides what is already on the public record at this time,” Warner said.

If convicted, Allen, a retired miner—whose own cell service is provided by Verizon, according to public records—faces up to 20 years in prison. Reached by phone, Allen’s lawyer, Stevens J. Jacobs, declined to provide The Daily Beast with a statement or comment on the case.

Allen’s arrest came less than a week after improvised explosive devices were discovered at a Verizon store in Cheboygan, Michigan and an AT&T store in Sault Ste. Marie. They had been placed in U.S. Postal Service Priority Mail boxes, which were sealed with black duct tape. Each of the IEDs “consisted of a metal pipe nipple with two metal end caps,” and contained “metal spheres and nails,” according to the complaint.

“Hardened objects such as these enhance the explosive effect, propelling fragments of metal outwards at high velocities which can cause additional damage and injuries,” states the complaint.

A set of handcuffs had been placed in both boxes. The initials “HJ” were scrawled across one. “Handcuff Johnny” was written on the other. They each indicated that this was the “last warning,” and that the next delivery would occur during business hours. The acronym “CMT” was also found on the two boxes, which was identical to one seen on a series of notes found in late August at cell towers throughout Michigan’s Upper Peninsula.

“The letters each indicate that they are from the ‘Coalition for Moral Telecommunication (CMT)’ and were addressed to ‘AT&T, Verizon, and all other Carriers,’” according to the complaint. “In the letters, CMT claimed to be ‘almost thirty strong’ and was ‘prepared to travel throughout this Country and begin distroying [sic] inner city tower communication’ unless several demands were followed. One demand was that all ‘telecommunication containing immoral content must be stopped,’ which includes cursing, pornography, and ‘all manner of indecent communication.’ This demand had a time requirement of ‘six months.’ Another demand was payment of $5 million, which had a time requirement ‘within 180 days.’ The letters also noted that if one of its members were arrested, then ‘your problems will begin’ and the ‘price will go up one hundred times.’ The group claimed in the letter that its ‘reach’ was in 27 states. The letters also had ‘CMT 5101520TG’ at the bottom of them.”

The notes were placed inside polka-dot envelopes, which were placed inside ziploc bags, which were zip-tied to fences at each cell tower site. A little more than two weeks later, the pipe bombs appeared at the AT&T and Verizon stores.

It only took a few days for modern technology—the apparent focus of Allen’s fury—to help cops zero in on their suspect.

Investigators pored over surveillance video from cameras in the vicinity of the two stores targeted by IEDs. In one segment of footage, they spotted a white man with a limp and a wide-brimmed hat in a sporting goods store adjacent to the AT&T location in Sault Ste. Marie that received the pipe bomb. Video captured by another camera showed the same man placing a box outside the AT&T store about six minutes later. He drove off in a maroon Chevrolet Uplander minivan with the license plate SWFE503, from either California or Washington.

About two hours after leaving the scene, the same minivan crossed the Mackinac Bridge, according to the video footage cited in the complaint. This time, agents saw the plate was indeed issued in California. Roughly 30 minutes later, around 10:10 p.m., the same man was seen placing a box outside the Verizon store in Cheboygan.

However, California authorities couldn’t find the plate in their motor vehicles database because it was too old. That’s when investigators noticed the dealership badge on the rear of the car: Richardson Chevrolet Buick in Standish, Michigan.

FBI agents showed up at the dealership, where an employee “provided information on vehicles that had similar characteristics” to the one seen on surveillance video. Several of the maroon Chevy Uplanders were “eliminated from consideration” according to the complaint, because they had either been junked or the registered owners did not match the description of the suspect. But one vehicle seemed promising: a 2006 maroon Uplander owned by John Douglas Allen, whose driver’s license photo looked a lot like the man seen placing the bombs outside the AT&T and Verizon stores.

“John Allen’s license plate also is a disability license plate,” the complaint states. “John Allen, as depicted in the video footage near the AT&T Store in Sault Ste. Marie as well as in video footage from the Verizon Store in Cheboygan, appears to have a limp.”

Investigators then checked a database of automatic license plate readers, which placed Allen’s minivan near the scene of each incident, on the same dates and times. They speculated that Allen had swapped out his actual Michigan plate for a dummy, in an attempt to evade law enforcement.

FBI agents began surveilling Allen at home, and researched his background. They discovered that he had worked at a company called TG Chemicals, which seemed to offer a clue to the “TG” typed on the bottom of the threatening notes left at the cell towers.
