A Cambridge man without a gun license bought 150 rounds of ammunition at a Wilmington gun show and threatened to "use a firearm and ammunition to allegedly conduct a shooting spree," the Middlesex County District Attorney's office reports.

WBZ reports Brian Schwarztrauber, 54, has long ranted about the Democratic Party and quoted DA Marian Ryan as saying that the current charges of illegal possession of ammunition "really don’t reflect the dangerousness of this situation."

The dealer at the Northeast Gun Show who alleged sold Schwarztrauber ammunition was also charged, for selling it to somebody without a gun license, the DA's office reports.

According to prosecutors, Wilmington police were initially called to the Northeast Gun Show because Schwarztrauber was being disruptive; they initially put him in protective custody because he was really drunk.

But then Cambridge Police called and said they were looking for him because of "statements allegedly made by the defendant indicating that he was going to use a firearm and ammunition to allegedly conduct a shooting spree," the DA's office says.

Armed with a search warrant, Cambridge Police found more rounds of ammunition in his Cambridge home, and charged him with illegal possession of ammunition as well. A Cambridge District Court judge set his bail on that charge at $25,000; he has yet to be arraigned on the Wilmington charge.

The DA's office adds:

Police located the vendor, identified as Stephen Fowler, 69 of Guilford, Connecticut, on March 2 and charged him after an investigation into the sale of the ammunition on March 3. Fowler was charged with selling ammunition without complying with the requirements relating to Firearms Identifications Cards.

Innocent, etc.
