The blast caused no injuries and minor property damage to the house, including a broken window. The bombing was the latest incident in an ongoing domestic dispute between Consiglio and his ex-wife, who divorced in October 2017.

In February, Consiglio threatened to “put a bullet” in his former wife’s head, according to court documents. As a result, he was charged with terroristic threatening, a misdemeanor crime punishable with up to a $2,500 fine and community service. During his initial court appearance, he was ordered not to have any contact with his ex-wife. He was then released on $500 unsecured bond. Consiglio was awaiting arraignment on these charges at the time of the bombing.

William Ivone, the brother of Consiglio’s ex-wife, was inside the house at the time of the bombing. He reportedly dropped to the ground after hearing the device detonate. Ivone looked outside and noticed Consiglio riding away on a bicycle. He immediately called police and identified Consiglio as the alleged perpetrator, describing him as “sick in the head.” Officers with the New Castle County Department, as well as a Delaware State Fire Marshal and agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives, responded to the scene. Neighbors were asked to shelter in place as police deployed a bomb robot to check for additional explosive devices. They were finally able to leave their homes around noon that same day.

Based on information provided by the witness, police converged on Consiglio’s Baltimore Avenue residence, which is less than a mile away from his ex-wife’s home. Consiglio was arrested and police began searching the house for evidence related to the bombing.

Inside the house, authorities found two handguns, a compound bow, a crossbow, a nightstick, brass knuckles, a samurai sword and several knives with blades ranging from six to 10 inches. Police also observed ammunition, arrows, and a “homemade” gun. Consiglio reportedly has a previous felony conviction which prohibits him from possessing any weapons.

Authorities also seized three improvised explosive devices similar in design to the one that detonated at the Cypress Avenue residence. The device that exploded was described as being four inches long and 1.5 inches in diameter, wrapped in black tape and capped with silver tape on each end. Investigators also found a fourth device, slightly smaller, under a dining room table in Consiglio’s home. Next to this device, there were several .12 gauge shotgun shells that had been cut open to gather the gun powder inside to use as explosive filler for the bombs. Other bomb-making items were found in the home including ball bearings, BBs, duct tape, Teflon pipe tape and model rocket engines.

Consiglio, who is an apparent white supremacist, has a Nazi Iron Cross with “SS” lightning bolts at the center tattooed on his neck. A photo of Consiglio on his Facebook page shows him wearing a black t-shirt with what appears to be an Aryan Fist (representing “white power”) on a shield emblazoned on the front.

Authorities have initially charged Consiglio with three counts of manufacturing, possession, use of an explosive device, and numerous weapons charges. Additional charges are pending.

In January, the Southern Poverty Law Center warned that domestic extremists often commit domestic violence related attacks against family members. While not directly related, the perpetrators extremist ideology is believed to serve as a foundation for using violence as an acceptable means to avenge grievances against perceived enemies, including personal vendettas against family members and friends.
