Court of Appeals for the Seventh Circuit November 18, 1993, 93-1423 and 93-1424 (United States v. Richard F. Tylkowski and Timothy P. Tylkowski)

KANNE, Circuit Judge.

In this case a father (Richard Tylkowski) and his son (Timothy Tylkowski) were convicted of a variety of firearms violations arising out of the sale of five M-ll semi-automatic rifles which had been converted into fully automatic machine guns. Richard claims the evidence against him was primarily circumstantial and insufficient for a conviction.
