New federal charges have been brought against the man authorities say sold the gun to the man charged with killed Sgt. Tim Chapin as well as three other men.
A new 21-page indictment names Kevin Dawson as well as Jack Wardlaw and Carl and Richard Monroe.
It says they sold firearms without getting a license "to avoid government oversight, tax consequences and the necessity for making background checks before selling firearms."
The indictment says they advertised in publications, business cards and word of mouth.
It says:
in January 2009, Wardlaw invested at least $15,000 with Dawson in the firearms business
On April 18, 2009, Dawson purchased multiple firearms from Austin Crow III
In March 2010, Wardlaw purchased multiple firearms from Yogey's Bunker
On Sept. 10, 2010, Dawson purchased multiple firearms from Globo Loan.
On Jan. 20, 2011, and Feb. 17, 2011, Richard Monroe purchased multiple firearms from AAAA Pawn Shop and Trading Post.
The indictments list dates that those charged allegedly sold firearms to individuals.
It was also charged that Dawson lied to authorities during a bankruptcy case.
It lists 323 weapons allegedly handled by the group and asks that they be forfeited or, if sold, there be a "substitute" forfeiture.
Prosecutor Terra Bay said the gun-selling conspiracy carries up to five years in federal prison. One of the charges carries up to 20 years.
Dawson is represented by Lee Ortwein, Wardlaw by Jerry Summers and Richard Monroe by Mike Caputo. Carl Monroe received a court-appointed attorney.
All were released on bond.
Trial date is Aug. 20.
