MINNEAPOLIS — A Minnesota man who recently confessed to abducting, sexually assaulting and killing 11-year-old Jacob Wetterling 27 years ago is due to be sentenced on a child pornography charge.

Fifty-three-year-old Danny Heinrich is due in Federal court Nov. 21.

He led authorities to Jacob’s remains this summer as part of a plea bargain that ended a mystery that had haunted Minnesota for nearly three decades. In return, prosecutors agreed not to charge Heinrich with murder.

The plea bargain calls for a sentence of 20 years, the maximum the law allows on the child pornography count.

Jacob was abducted near his home in the central Minnesota community of St. Joseph on Oct. 22, 1989.

Heinrich was arrested on child pornography charges last year but kept Jacob’s fate secret until this summer.
