It was day four of Brogan Rafferty's trial in the Craigslist case. Rafferty, now 17, is charged with felony counts of murder and is facing life in prison. 

On Wednesday, Special FBI Agent Bonnie Hartmann was on the stand to talk about the weapons founds in Rafferty's room. Hartmann said she found a .22 caliber handgun, two knives, a sawed-off shotgun in a briefcase. Another shotgun was found behind a door.

Jonathan Gardner, a firearms identification expert with the Bureau of Criminal Identification, examined the guns and the bullets found at the crime scenes in Noble county, where three me were killed after being lured to a farm with a bogus Craigslist ad for work. 

Richard Beasley is also facing murder charges for being involved with the deaths in Noble County. Prosecutors are seeking the death penalty. It's said that Beasley was a mentor to Rafferty. 

"Due to the damage on these bullets and the lack of identifiable markings, I can't say these bullets were fired from this gun,"  Gardner said, according to a NewsNet5.com story.
