Convicted Sex Offender Sentenced to Federal Prison for Failing to Register


A convicted sex offender who lived and worked in Iowa for about 14 months without registering as a sex offender was sentenced on September 9, 2021, to more than a year in federal prison.

Charles Gregory, age 50, from Charles City, Iowa, and previously from Illinois, received the prison term after a January 5, 2021 guilty plea to one count of failing to register as a sex offender.

Information disclosed at the sentencing hearing showed that Gregory is required to register as a sex offender for life because he was convicted of multiple counts of aggravated sexual assault in 1990.  Gregory was also convicted of failing to register in Illinois state court in 2000.  In May 2018, Gregory began working and living in Iowa.  He continued to work and live in Iowa until September 2019.  Gregory’s failure to register during this time was discovered when he was arrested for operating a motor vehicle while intoxicated in Bremer County.  He was eventually convicted of that offense, his second such conviction.
