JOHNSTOWN — A federal jury on Wednesday convicted Morrisdale resident Clint Addleman, 49, on all charges related to a 2019 bombing that killed a Clearfield woman.

Shawna Carlson, 34, died after a package delivered to her home exploded, resulting in a fire that totaled the two-story apartment building where she lived.

After hearing seven days of testimony and spending about 2.5 hours deliberating, a jury of six women and six men found Addleman guilty on all four charges against him: possession of an unregistered destructive device, conspiracy to destroy property by explosive or fire, malicious destruction of property resulting in death and conspiracy to distribute methamphetamine.

U.S. District Judge Stephanie Haines scheduled Addleman’s sentencing for 10:30 a.m. July 22. Addleman appeared stoic when exiting the courtroom, while sniffles were heard from his family members who were in court for the proceedings.

According to court documents, Addleman fronted Carlson $800 in methamphetamine, but Carlson never paid Addleman for the drugs.

Addleman frequently threatened her and eventually created an explosive wrapped inside a package that co-conspirator, Kris Joseph Nevling, left on Carlson’s doorstep Oct. 4, 2019.

When Carlson pressed a button on the device, the explosive released plastic shards that killed her and set fire to the apartment.

During closing arguments, U.S. Attorney Shaun Sweeney said Addleman’s case was “as serious as it gets.”

Sweeney said the jury’s first challenge was where to begin their deliberation.

The package was addressed to a star symbol — Carlson’s nickname — in stenciled writing with other messages, including “Sorry it took so long” and “I rec(orded) a message for you. Play it.” Carlson had recently celebrated her birthday.

Sweeney said the package was “not randomly placed in Clearfield.”

Someone “wanted to kill her with high explosives and take down the building,” he said. “Why would anyone want to do it to Carlson?”

He said Carlson was a troubled woman who was addicted to methamphetamine and lived alone, keeping to a small group of friends, based on previous testimonies.

If a customer owes a drug dealer money, Sweeney said that the dealer can’t sue or seek out the police. They have to take care of the situation themselves and instill fear in customers, he said.

According to Addleman’s Facebook profile, which was displayed for jury observation, his bio states, “BAD MOTHER F*****, WHO WONT TAKE S*** & WILL MAKE U WISHED YEAH NEVER CAME ACROSS MY PATH.”

Based on Addleman’s bio, Sweeney said it’s “extremely important for people to fear him,” referring to Addleman’s profile picture, which reads, “I’ve come to do the devil’s work.”

Addleman typically conducted his dealings inside a secret room located in his basement, Sweeney said, but Addleman visited Carlson’s home to deliver drugs.

A trial witness stated that Addleman broke into Carlson’s apartment three times and threatened, “I’m going to kill you, one way or another,” Sweeney said.

Through text exchanges, Sweeney said that Carlson expressed her fear to a close friend, telling him that “I’m going to take the bullet fed to me. I think I’m going to end up dead for real.”

Looking at evidence from the house explosion, Sweeney said a piece of fabric with explosive materials was stuck to an exterior wall of a real estate building located across the street from Carlson. That material “has no business in a residential area,” he told the jury.

TNT explosives require a detonator to set them off, he said, involving blasting caps and other chemicals that Addleman stored in his home, an evaluation based on witness testimonies.

And those elements could fit inside the package that was delivered outside of Carlson’s house, Sweeney said.

Defense closing arguments

In his closing argument, defense attorney Daniel H. Goldman of Alexandria, Va., said rumors and suspicions were woven into theories created by the prosecution.

“The government is asking you to believe theories that he (Addleman) carefully wiped his fingerprints off the bomb and an unidentified person placed (it) at the house, she (Carlson) pressed the button that resulted in her death,” Goldman said.

He said the government meticulously built a theory using 40-plus witnesses so the jury would then find Addleman guilty.

Considering some of the witnesses who testified were involved in drug trades, he said the jury must evaluate if they were under the influence during investigations, creating unreliable narratives in their statements.

According to Goldman, there were three types of witness testimonies during Addleman’s jury trial: individuals who provided objective accounts with no motives; those who echoed government theories or their own ideas; and witnesses who were lying on the stand.

An inmate who knew Addleman for a short period in prison shared a story about Addleman’s involvement that conveniently fit the government’s theory, Goldman said.

Another testimony came from a tenant of Addleman’s previous home, who noted that Addleman’s secret drug-dealing room was white, and occupants had to step up three feet to enter. Yet, pictures of the room show it has purple and yellow walls and a nonexistent ledge.

Goldman said that Addleman’s longtime friends didn’t testify to seeing blasting caps — or any explosives other than fireworks — in his basement.

“People with the most elaborate stories have the most to gain,” Goldman said

Addleman’s longtime girlfriend’s father classified Addleman as a “97% guy,” Goldman said, meaning that he wasn’t capable of building an explosive device or wiping his fingerprints from the explosive device.

Goldman asked the jury, “Do you believe Addleman is physically and intellectually capable of building this device?”

Although Addleman played into the mastermind rumors on his Facebook page, “that doesn’t make him the person who actually did it,” Goldman said.

Nevling, who was convicted in August for his role in the killing, is scheduled for sentencing on March 25.
