Federal authorities arrested a 21-year-old Pennsylvania man on Tuesday after an investigation revealed alleged ties to ISIS and plans for a violent attack, according to court documents.
A semiautomatic rifle, five magazines, and 190 rounds of ammunition were seized during the arrest, which followed a tip to the FBI and months of surveillance. The suspect, Jonathan Hunter Kramer of Valencia, Pennsylvania, had previously been adjudicated delinquent in 2023 for an alleged plot to commit a mass-casualty incident and possession of child sexual abuse material, records show.
Core Developments
- Kramer was taken into custody on September 12 after FBI agents tracked his movements to a hotel and a sporting goods store, where he allegedly purchased a firearm.
- He had allegedly used the online alias “Hamza Al Rashid” and claimed affiliation with ISIS, according to a federal criminal complaint.
Investigation Timeline & Evidence
Authorities allege Kramer’s alleged extremist activities began in 2023, when he was charged as a juvenile in Pennsylvania for an alleged mass-casualty plot and child sexual abuse material possession. He was released from detention in early 2024, after which an anonymous tipster contacted the FBI with concerns about his behavior.
The tip led to renewed surveillance, during which agents observed Kramer purchasing a disposable phone and meeting an unknown individual in a parking lot. He was later seen at a sporting goods store before agents intercepted him outside. A search warrant executed at the scene and his hotel room yielded the firearm and ammunition, court documents state.
Legal Charges & Allegations
Kramer faces a single federal charge of receiving a firearm and ammunition with the intent to commit a felony or federal crime of terrorism. Prosecutors allege he knew or had reasonable cause to believe the items would be used to support ISIS or another designated foreign terrorist organization.
The complaint does not specify whether Kramer had direct contact with ISIS members or whether his alleged affiliation was symbolic. His alleged statements about preparing for a “mission” and needing a “weapon” were cited as evidence of intent, though no specific target or timeline was disclosed in court filings.
Background & Prior Legal History
Kramer’s 2023 adjudication as a juvenile involved allegations of a mass-casualty plot and child sexual abuse material possession, according to the Justice Department. The nature of the mass-casualty allegations and any connection to his current case remain unclear in public records.
The FBI has not commented on whether Kramer acted alone or received external support. The investigation is ongoing, and additional charges may be filed as details emerge.
