Federal Jury Finds Lead Defendant and Mastermind Behind Targeted Bombing That Killed Clearfield Woman Guilty on All Charged Counts

JOHNSTOWN, Pa. - After deliberating for two hours, a federal jury on March 18, 2026, found Clint Addleman, 49, of Clearfield, Pennsylvania, guilty on charges of possession of an unregistered destructive device, conspiracy to maliciously destroy property by explosive or fire, malicious destruction of property by explosive or fire resulting in death, and conspiracy to distribute methamphetamine, United States Attorney Troy Rivetti announced today. Addleman's co-defendant, Kris Nevling, was convicted by jury trial in August 2025.

Addleman was tried before United States District Judge Stephanie L. Haines in Johnstown, Pennsylvania.

The evidence presented during the seven-day trial established that, in and around early October 2019, Addleman and his co-defendant Nevling aided and abetted one another in the construction and possession of a destructive device-a bomb-which was subsequently concealed inside a package addressed to the victim using her nickname. At approximately 4:30 a.m. on October 4, 2019, the package containing the bomb was delivered and left outside of the door to the victim's first floor apartment in a multi-unit rental property on East Market Street in Clearfield. Later that morning, the bomb detonated inside the victim's apartment, killing the victim and causing a fire that destroyed the building. Trial evidence established that the victim owed Addleman an outstanding drug debt of approximately $1,000.

The jury also determined the victim's death to be a result of the commission of the conspiring to maliciously destroy and malicious destruction of property by explosive or fire offenses. Addleman was additionally convicted on a charge of conspiring to distribute a quantity of methamphetamine between January and October 2019.

Judge Haines scheduled Addleman's sentencing for July 22, 2026. The law provides for a maximum total sentence of up to life in prison, a fine of up to $250,000, or both. Under the federal Sentencing Guidelines, the actual sentence imposed is based on the seriousness of the offenses and the prior criminal history, if any, of the defendant.

In August 2025, a jury also found Nevling guilty of both conspiracy to maliciously destroy property by explosive or fire-similarly determining the victim's death to be a result of this offense-and possession of an unregistered destructive device. Nevling is scheduled to be sentenced on March 25, 2026.

Assistant United States Attorneys Maureen Sheehan-Balchon and Samantha A. Stewart and Special Assistant United States Attorney Shaun E. Sweeney prosecuted this case on behalf of the government.

The Bureau of Alcohol, Tobacco, Firearms and Explosives, Clearfield Regional Police Department, and Pennsylvania State Police conducted the investigation that led to the prosecution of Addleman.
