United States v. Lee
141 F. 3d 1171, 1998 WL 165722 (8th Cir.)
Lee pled guilty to sexual abuse of a minor. The trial judge imposed a greater sentence under the federal Sentencing Guidelines because the victim was "vulnerable due to . . . mental condition." The court of appeals affirmed.
The victim had FAS, an IQ of 65, and functioned as a 10-year-old.
Lee and the victim apparently had a long-standing relationship and had had a child together.
