Sioux City, Iowa — The U-S Attorney’s Office for the Northern District of Iowa reports a western Iowa man was sentenced to federal prison for failing to register as a sex offender in two states. 44-year-old Tyrone Haskell Tyndall, of Onawa, was sentenced to slightly more than two-years behind bars after admitting he failed to register with the Monona County Sheriff’s Office. He’d been convicted in 2004 of sexually abusing a child in Nebraska. Tyndall also admitted failing to register in Nebraska where he also lived from 2018 to 2019.

Tyndall admitted to violating his requirement to register as a sex offender in Iowa and Nebraska from July 2018 to August 2019, even though he lived in both states during this timeframe. Tyndall was sentenced in Sioux City by United States District Court Chief Judge Leonard T. Strand. Tyndall was sentenced to 27 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.

Tyndall 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 Attorneys Kevin Fletcher and Ron Timmons and investigated by the United States Marshals Service.
