Michael Christopher Estes, 46, had been convicted in 2016 of assault with intent to inflict serious bodily injury.
He reported to jail on Sept. 21 and was released a week later on Sept. 28, although he was sentenced to serve between 10 and 21 months, according to North Carolina state jail records.
Estes was sentenced for walking onto a man’s property and chasing him into a trailer, where he attacked him with a 16-inch knife and hatchet on July 31, 2015, the Asheville Citizen-Times reported.
He reportedly caused lacerations to the victim’s right temple, left tricep and on his left cheek from mouth to earlobe.
Estes was arrested most recently on Oct. 6 for attempted malicious use of explosive materials and unlawful possession of explosive materials in an airport.
He allegedly placed a homemade bomb created using a Mason jar full of ammonium nitrate, Sterno fuels, nails and a .410 gauge Winchester shotgun cartridge at the Asheville Regional Airport, according to a criminal complaint report filed in the Western District Court of North Carolina.
There was an alarm clock taped to the outside of the jar with matches pressed between the glass and one of the clock’s bells to make the matches strike and set off the device. The clock was set to go off at 6 o’clock.
A maintenance employee spotted Estes days earlier, wearing all black clothes, in a wooded area across the street from the airport.
Investigators searched the area and discovered a green backpack and black tool bag partially covered with leaves, according to court reports.
After determining there was no bomb inside, investigators observed the contents — a roll of Gorilla Tape, Kobalt gloves, Sterno Firestar Gel, what appeared to be an alarm clock bell and a bag of red .410 gauge shotgun shells.
All of the items matched what was used in the device at the Asheville Airport.
Investigators checked surveillance camera footage at local Walmart and Lowe’s stores and identified the suspect.
They also visited an REI sporting goods store where Estes had purchased the backpack. While there was no security camera footage available, Estes had paid cash and used an REI membership number when paying, revealing his identity to investigators.
Estes was arrested one day after the device was discovered.
Court records show he waived his Miranda rights and spoke openly to police, admitting that he placed the device at the airport and revealing where he bought his supplies.
He claimed he was preparing to “fight a war on U.S. soil” but insists he did not actually set the clock to go off.
