Jeffery Landheer, age 46, of Mason City, Iowa, has been charged with one count of receipt of child pornography and six counts of possession of child pornography. The charges are contained in an Indictment unsealed on March 2, 2017, in United States District Court in Cedar Rapids.

If convicted, Landheer faces a mandatory minimum sentence of 5 years’ imprisonment and a possible maximum sentence of 140 years’ imprisonment, a $1,750,000 fine, $25,700 in special assessments, and at least 5 years and up to life on supervised release following any imprisonment.


Landheer appeared for a detention hearing today in federal court in Cedar Rapids, and the court ordered his release on bond. Landheer’s next appearance for trial is set for May 1, 2017.
