A federal judge has sentenced Brian DiPippa, 37, and his wife, Krystal DiPippa, 42, of Pittsburgh, to prison and probation, respectively, for their roles in a 2023 bombing attack targeting a conservative event at the University of Pittsburgh. The attack, linked to Antifa, injured several police officers and highlighted the growing domestic terrorism threat from extremist groups.
U.S. District Court Judge J. Nicholas Ranjan sentenced Brian DiPippa to five years in prison for conspiracy and obstruction of law enforcement. As part of a plea deal, a charge of using explosives to commit a federal felony was dismissed. Krystal DiPippa received three years of probation and must complete 80 hours of community service after pleading guilty to obstruction of law enforcement. Her conspiracy charge was also dropped as part of a plea agreement.
The couple was ordered to pay $1,400 in restitution to the University of Pittsburgh and $47,284 to a police officer injured in the attack.
On April 18, 2023, Brian DiPippa ignited two homemade incendiary smoke devices near a crowd attending a speech by conservative commentator Michael Knowles. Later, concealed by his wife, Brian hurled an explosive firework into a group of police officers forming a barrier, injuring multiple officers.
A female sergeant required back surgery and sustained hearing loss and burns. She described Brian as a “homegrown terrorist” during sentencing, emphasizing his intent to harm law enforcement.
The DiPippas were active members of Antifa, a far-left extremist group. Authorities tied the couple to a local anarchist cell through surveillance and materials recovered from their home, including instructions for making explosives and incendiary devices.
Brian’s involvement was further confirmed through surveillance at anarchist meetings, purchases of explosive materials, and forensic evidence, including a positive test for the RDX explosive compound.
Assistant U.S. Attorney Shaun E. Sweeney highlighted the severity of the attack, noting its premeditated nature and the danger posed to law enforcement and the public.
“These sentencings send a clear message that the FBI and our partners will use all available tools to bring to justice those who seek to injure, maim, or attack law enforcement officers,” said FBI Pittsburgh Special Agent in Charge Kevin Rojek.
The DiPippas’ sentencing has drawn criticism and support along ideological lines. Far-left organizations, including the Civil Liberties Defense Center, defended the couple, claiming the prosecution was politically motivated. Conversely, officials and community leaders emphasized the importance of holding violent extremists accountable to deter future attacks.
This case underscores the ongoing threat posed by domestic extremist groups and the resolve of law enforcement to combat such dangers. Investigations were led by the FBI, the Joint Terrorism Task Force, and local police agencies.
