Investigators say the suspect in a Schuylkill County homicide investigation confessed to the crime after the body was found in a wooded area by ATV riders in Blythe Township.
State Police say Jason "Jay" Hahn, 22, was found dead off of Silver Creek Road near New Philadelphia around 5 p.m. Saturday.
Police have charged his friend, Ethan Sullivan, 20, of Saint Clair, with criminal homicide and other charges.
Investigators say Sullivan hit Hahn in the head three times with a two foot metal bar after an argument last week.
Hahn's friend and roommate, Derek Snyder, said friends saw Hahn leave a party at their Andreas home on June 14 with Sullivan.
That was the last time anyone saw him alive.
"I just want to know why," said Snyder. " I just want to know what happened and what could have led to it. That's all I want to know."
State Police say on June 18, Sullivan was arrested and locked up on unrelated crimes, and confessed to the homicide after Hahn's body was found.
According to court documents, Sullivan drove to the home on June 15 around 1 a.m. and had a conversation with Hahn.
Soon after, investigators say the two drove off in a Jeep that Sullivan allegedly stole.
Police say they stopped at a wooded area in New Blythe Township.
That's where Sullivan is accused of repeatedly hitting Hahn.
After Hahn fell to the ground, investigators claim Hahn wrapped the body in a tarp, threw it down a dirt embankment, and then placed logs on top.
Police also accuse Sullivan of taking cash, cards, and identification materials from Hahn's wallet.
Sullivan also allegedly removed the battery from Hahn's cell phone.
Then, investigators say, Sullivan lit the Jeep on fire and took off on foot.
Those accusations are startling to Sullivan's friends.
Snyder said Sullivan was a mutual friend, and occasionally stayed at the house with him and his family.
He never thought of his friend as the violent type.
"I didn't see Ethan as that type of person," said Snyder. "I've known Ethan over a year and I never saw him as violent. He never had any anger, outbursts, nothing like that towards me. I never saw it."
Snyder says he ran a small t-shirt and jewelry business called "Happy Hippie Wear" with Hahn.
The two had planned to drive cross country to sell their goods at concerts and festivals this summer.
"He was just the nicest kid," said Snyder. "Always helpful. He did everything around the house for my mom."
Snyder says he'll miss Hahn's sense of humor most of all.
"Funny, also funny. He was known for random one liners just to crack you up out of nowhere. He was very quiet, but when he said something, it was always great."
Hahn's ex-girlfriend, Robyn Erney, tearfully said when she learned of Hahn's death Sunday morning. "I didn't know what to think," said Erney. "I don't want to believe it. I was hoping he'd come home safe, we all thought he was out camping but he just never came home."
She said the two had dated on and off for about seven years.
"He was a very good guy, he didn't deserve this. He didn't deserve any of it. That kid deserves to rot in jail," said Erney.
Sullivan is locked up in Schuylkill County Prison without bail on charges of criminal homicide, aggravated assault, robbery, simple assault, theft by unlawful taking and recklessly endangering another person.
