A Sioux Center man faces a felony charge after authorities allege he failed to report a change in employment as required by the Iowa Sex Offender Registry.
The Sioux County Sheriff’s Office says 26-year-old Jacob Mathew Trammel was arrested at about 11:30 a.m. Saturday, August 22.
Officer Allegedly Observed Trammel at New Job
According to a criminal complaint, a Sioux County deputy was off duty on August 14 when he observed Trammel working at the McDonald’s restaurant on North Main Avenue in Sioux Center.
The deputy said he recognized Trammel through his duties supervising the Iowa Sex Offender Registry in Sioux County. The complaint identifies Trammel as a Tier 1 sex offender who is required to report a change in employment to the sheriff’s office within three business days.
The deputy reportedly reviewed Trammel’s registry information and found that his only listed employment was at a Shell gas station. The complaint says no employment at McDonald’s had been reported.
Authorities say the same deputy was on duty August 22 when he again observed Trammel working at McDonald’s. When contacted, Trammel allegedly acknowledged that he had started working there more than a week earlier and said he had forgotten to notify the sheriff’s office.
Complaint Cites Previous Conviction
Court documents say Trammel was previously convicted of a sex offender registry violation in Sioux County District Court on December 5, 2024.
Trammel was transported to the Sioux County Jail and charged with a second or subsequent sex offender registry violation, a Class D felony.
He was released on Saturday after posting a $5,000 bond.
