A chilling incident in Derry Township, Westmoreland County, has led to the arrest of a local man accused of orchestrating a dangerous explosive device intended for a riding lawnmower. Authorities report that John M. Miller, 54, of Derry Township, now faces serious felony charges after allegedly rigging a 12-gauge shotgun shell to the mower's ignition system, using a piece of fishing line to ensure its detonation.
The harrowing discovery unfolded in mid-May when the owner of the riding lawnmower attempted to start the machine.
Instead of the usual hum, a violent explosion rocked the area, narrowly missing the individual. While details on specific injuries are not immediately available, the intent behind such a device points to a clear and present danger.
State police investigators meticulously pieced together the evidence, revealing a disturbing level of premeditation.
According to court documents, Miller allegedly attached a single 12-gauge shotgun shell to the lawnmower's ignition switch. The ingenious, yet malicious, setup involved a length of fishing line, ensuring that as the ignition key turned, the shell would be triggered, creating a potentially lethal blast.
The motive behind this shocking act appears to stem from ongoing disputes between Miller and the property owners.
Just days prior to the explosion, Miller had allegedly slashed a tire on a pickup truck at the same property. Furthermore, police reports indicate that Miller had previously issued terrifying threats, including a promise to kill the victim's dog. These alleged prior acts paint a picture of escalating animosity that culminated in the explosive device.
Miller was apprehended on Thursday and subsequently arraigned before District Judge Mark R.
Sorice. He now faces a litany of charges, including felony counts of possession of an explosive device, risking catastrophe, and terroristic threats. Additionally, he has been charged with misdemeanor counts of simple assault. Following his arraignment, Miller was committed to jail after failing to post his $50,000 bail, highlighting the severity of the allegations against him.
A preliminary hearing is scheduled for June 27, where more details of this alarming case are expected to emerge.
This incident serves as a stark reminder of the dangers that can arise from personal disputes, especially when they escalate to such extreme and life-threatening measures. Law enforcement officials continue to investigate, ensuring the safety of the community and bringing those responsible for such acts to justice.
