Article is a bit limited but they found rounds at his house, not in the car which for any regular shooter isn’t that far fetched. He did have multiple fully loaded mags, body armor, and tried to pass off creds to the cop that he was an air marshal however.
Gotta love the media. People who shoot a lot or want to buy in bulk to save money when the metals prices were bouncing all over the place just split big boxes. I think I have about 2,000 rounds of .22 at my house purely for targets.
