A 32-year-old East Whiteland Township man who was arrested carrying a concealed, loaded handgun near the Chester County Courthouse during a June 2025 rally in West Chester will spend more than three years in federal prison for possessing homemade explosive devices found at his home two days later.

U.S. Attorney for the Eastern District of Pennsylvania David Metcalf announced Tuesday that Kevin Joseph Krebs was sentenced to 37 months in prison and 36 months of supervised release. U.S. District Judge Mary Kay Costello issued the sentence.

The case began in June of 2025, when West Chester Police Officer Adriana Zeiders was on patrol at the corner of Gay and High streets. Another officer alerted her to a report of a man in a yellow raincoat with what appeared to be a concealed gun.

Zeiders spotted Krebs almost immediately, about half a block from the historic courthouse where a No Kings rally was set to begin.

Krebs was carrying a fully loaded Sig Sauer .32-caliber semiautomatic handgun in his waistband, along with three loaded handgun magazines, six loaded assault rifle magazines, a rifle bayonet, pepper spray, a ski mask and gloves, according to the arrest affidavit. He was charged with carrying a firearm without a license, a first-degree misdemeanor.

Two days later, Chester County detectives executed a search warrant at Krebs's Conestoga Road residence in East Whiteland Township. In the garage, they found what appeared to be a pipe bomb. The Montgomery County Bomb Disposal Unit ultimately recovered 13 improvised explosive devices from the home.

Bomb technicians determined the pipe bomb contained nails and screws used as shrapnel. Of the materials recovered, technicians classified six as destructive devices and identified 10 improvised explosive detonators. Investigators also found eight one-pound containers of suspected ammonium nitrate and aluminum powder, a binary explosive mixture classified as a regulated explosive, according to Chester County District Attorney Chris deBarrena-Sarobe.

Additional items at the home included another firearm, a homemade silencer, a 3D printer and what appeared to be two 3D-printed machine gun conversion devices that could turn some firearms into fully automatic weapons, deBarrena-Sarobe said. Investigators also found sketches of explosive devices and tactical vests.

Krebs was charged in December 2025 by the Eastern District of Pennsylvania on one count of possession of an unregistered firearm or destructive device and pleaded guilty the same month.

The federal case was investigated by the Chester County District Attorney's Office, FBI Philadelphia's Newtown Square Resident Agency, and the West Chester Police Department, with assistance from the Montgomery County, FBI and ATF bomb squads.

Pennsylvania's state case against Krebs remains pending. Dana Moore, director of communications for the Chester County DA's Office, said Wednesday that the office "will carefully review the facts and circumstances, including the disposition of the federal case, before making a determination regarding the pending charges in Chester County."

State charges include 13 counts of weapons of mass destruction, 13 counts of possessing an instrument of crime, and carrying a concealed handgun without a license. No hearing date has been scheduled for the state case.
