Dayton, Ohio - A friend of the Dayton gunman who killed nine people told federal agents he bought him body armour, a gun accessory and a 100-round magazine earlier this year, according to a court document unsealed Monday.
According to the affidavit, Kollie acknowledged purchasing three items used by Betts during the August 4 mass shooting: body armor, upper receiver that was attached to the AM-15 weapon, and a 100-round double drum magazine.
The FBI said last week that Betts, had a history of violent obsessions and had mused about committing mass murder before his rampage in Dayton's historic downtown.
The weapon was bought online from a dealer in Texas and shipped to another firearms dealer in the Dayton area, police said on the day of the shooting.
Unrelated to the federal charge, Kollie played a significant role in helping the Dayton gunman purchase, assemble, and hide items used in the mass murder. "Kollie and Betts allegedly assembled the AM-15 in Kollie's apartment approximately 10 weeks ago".
"During that first interview, Kollie allegedly told agents that he likes guns and now owns a handgun and a micro Draco pistol", reads the statement.
Kollie agreed to allow agents to search his home, and while inside, they say they smelled marijuana and observed in plain sight a bong and the Drago pistol.
The U.S. Attorney's office for southern OH said more information about the charge that is being unsealed will be released at a news conference Monday afternoon.
"Kollie indicated he purchased these items for Betts and stored them at his apartment to assist Betts in hiding them from Betts' parents", the statement explains.
He was also charged with possession of a firearm by an unlawful user of a controlled substance, according to court documents.
Kollie faces up to 15 years in prison if convicted, Glassman said.
Wickerham said the Federal Bureau of Investigation is still examining the cell phone Betts was carrying at the time of the attack.
Betts killed his sister and eight others and wounded 14, officials say.
