A Marshalltown man will likely face federal charges once an investigation of him is complete.
Marshalltown Police Department assisted a United States Postal Inspector Wednesday afternoon with an investigation of Cory Baker, 40.
United States Postal Inspector Linda Jensen said the records of why Baker is being investigated are sealed until a federal grand jury in Iowa's southern district looks over the case. Should the jury opt for indictment, it will allow her to apply for warrants.
Police were at Baker's home,1014 S. Sixth St., assisting when they discovered Baker, a registered sex offender, had failed to comply with the stipulations set forth by the Marshall County Sheriff's Office.
As a tier three offender, Baker is required to check in with the sheriff's office every three months. He is also required to provide police with all relevant contact information.
While at Baker's home, an officer discovered that he has had a cell phone since 2008. Baker has been registered as a sex offender in Marshall County since March 2007 and failed to provide the number to that cell phone to police.
In 2000, Baker was convicted of possession of child pornography and sexual exploitation of a person between the ages of 14 and 17 in Polk County.
Police arrested Baker for failure to comply, his first such offense, an aggravated misdemeanor.
No federal charges have been filed against Baker as of Thursday afternoon. Jensen said the grand jury meets the third week of every month.
