New Castle County prosecutors announced Wednesday that Gregory Wierzbicki, 66, has been arrested on multiple firearms charges following an investigation into a series of threatening online posts. The posts, made on the Blue Sky app and Substack platform, called for violence against federal officials, including members of the U.S. Supreme Court.

Threatening posts and law‑enforcement response

According to the New Castle County State’s Attorney’s Office, Wierzbicki posted a message expressing a desire to surveil Supreme Court justices in order to learn their travel routes and “give them a scare.” Another post referenced a guillotine, and additional entries mentioned the formation of militias. Law‑enforcement officials treated the content as a credible threat and obtained a search warrant for Wierzbicki’s residence.

Search warrant yields weapons

During the execution of the warrant, investigators discovered several firearms inside the home. Because Wierzbicki was convicted of a felony burglary in 2006, state law prohibits him from possessing any firearm. The discovery of the weapons formed the basis for the current felony firearms charges.

Legal background

Delaware law classifies the unlawful possession of a firearm by a convicted felon as a third‑degree felony, punishable by up to five years in prison and a fine of up to $10,000. The State’s Attorney’s Office indicated that the charges reflect both the illegal possession and the potential danger posed by the threatening online statements.

Next steps in the case

Wierzbicki remains detained pending a hearing scheduled for next week. At that hearing, a judge will determine whether he will continue to be held in custody or be released on bond pending trial. The prosecutor’s office has not yet disclosed whether additional charges, such as making terroristic threats, will be filed.

Community reaction

Local residents expressed concern over the incident, noting the seriousness of threats directed at the nation’s highest courts. “We expect our community to be safe and to respect the rule of law,” said a spokesperson for the New Castle County Sheriff’s Office. “Any attempt to intimidate federal officials is taken very seriously and will be prosecuted to the full extent of the law.”

The case underscores the importance of monitoring online platforms for extremist content and reinforces the county’s commitment to enforcing existing firearms restrictions for individuals with prior felony convictions.
