An Alexandria, Va., man is accused of using Craigslist to find buyers for firearms.
Austin Birch, 19, is charged with illegally selling and possessing firearms and money laundering.
Virginia State Police began investigating Birch in February when a special agent came across a post offering firearms and assault weapons, authorities said. State and county police arranged several undercover meetings with Birch to purchase handguns, assault weapons, high-capacity magazines and body armor, authorities said.
One investigator posed as a convicted felon and made that known to Birch, who allegedly was still willing to sell, authorities said.
