Sioux City Man Sentenced to Prison for Failure to Register as a Sex Offender

For Immediate Release
U.S. Attorney's Office, Northern District of Iowa
In 2007, Cook was convicted of sexual abuse in Nebraska

A man who failed to register as a sex offender was sentenced on September 29, 2019, to 41 months’ in federal prison.

Charles Lee Cook, age 36, from Sioux City, received the prison term after an April 9, 2019, guilty plea to one count of failure to register as a sex offender.  

At the guilty plea, Cook admitted that from October 20, 2017, through November 18, 2018, he knowingly failed to register or update his registration as required by the Sex Offender Registration and Notification Act. The investigation showed that beginning in April 2018, Cook registered two different addresses in Sioux City, but failed to reside at either location. Cook is required to register as a sex offender due to a March 28, 2007, conviction for sexual abuse in the U.S. District Court for the District of Nebraska. 

Cook was sentenced in Sioux City by United States District Court Chief Judge Leonard T. Strand.  Cook was sentenced to 41 months’ imprisonment.  He must also serve a 5-year term of supervised release after the prison term.  There is no parole in the federal system.

Cook is being held in the United States Marshal’s custody until he can be transported to a federal prison.

The case was prosecuted by Assistant United States Attorney Kevin C. Fletcher and investigated by the United States Marshals Service.
