DES MOINES, Iowa (AP) — Ian Roberts, the former superintendent of Des Moines Public Schools, Iowa's largest school district, is expected to plead guilty in federal court on Thursday to two charges. These charges include falsely claiming to be a U.S. citizen, which could result in a lengthy prison sentence and increase his risk of deportation.

Originally from Guyana and a former Olympic runner, Roberts had a notable career in urban education, leading the Des Moines district for two years before facing legal troubles. His detainment by federal immigration officers on September 26 shocked the community and garnered national attention due to his previous criminal charges and reports of falsified credentials.

Initially entering a plea of not guilty, Roberts has now signed a plea agreement, which includes admitting to making false statements to secure employment and unlawfully possessing firearms. The combined charges carry a potential maximum of 20 years in prison.

Roberts was apprehended during a targeted Immigration and Customs Enforcement operation after allegedly fleeing from agents in a school-issued Jeep Cherokee. A loaded handgun was found hidden in the vehicle, along with a significant amount of cash.

According to the indictment, Roberts knowingly submitted a false Employment Eligibility Verification form claiming to be a U.S. citizen, which could result in a five-year prison sentence. Additionally, he faces multiple counts related to firearm possession, which include guns found in his car and home.

The plea agreement reveals that Roberts is aware of the potential for deportation following his sentence. His attorneys previously claimed he believed his immigration status had been resolved.

As part of the plea deal, U.S. prosecutors have indicated that they will recommend leniency, although the final decision on sentencing rests with the judge.
