According to findlaw.com, there is no 18 USC 1243. I strongly suspect there is some basis for federal jurisdiction, since I'm fairly sure the feds have prosecuted such crimes in the past. But, as I read 18 USC 2243, it doesn't look as if it provides jurisdiction.

I misquoted, it's this: TITLE 18 - CRIMES AND CRIMINAL PROCEDURE
PART I - CRIMES
CHAPTER 109A - SEXUAL ABUSE

Sec. 2243. Sexual abuse of a minor or ward
