For Immediate Release
U.S. Attorney's Office, Northern District of Iowa

A man who hid a gun that his brother used in a murder was sentenced January 30, 2013, to 8 years in federal prison.

Winsdell Nowelin Lamb, age 25, from Mason City, Iowa, received the prison term after a September 12, 2012, guilty plea to one count of possession of a firearm by a felon.

On August 9, 2011, Lamb’s half-brother Jamaal Leslie shot and killed a man in Mason City. As Leslie fled the scene, he discarded the handgun which Lamb picked up. Lamb was later found hiding in the attic of a residence with the handgun. Lamb had previously been convicted of possession of marijuana with intent to deliver in 2008 and possession of marijuana in 2011, both felonies. At the time of the offense, Lamb was on escape status from the Beje Clark Residential Facility on these drug convictions.

Lamb was sentenced in Cedar Rapids by United States District Court Chief Judge Linda R. Reade. Lamb was sentenced to 96 months’ imprisonment. A special assessment of $100 was imposed. He must also serve a three-year term of supervised release after the prison term. There is no parole in the federal system.

Lamb will be returned to state prison in Iowa to complete his state drug sentences before being transferred to federal prison to serve his federal gun sentence.

This case was prosecuted as part of Project Safe Neighborhoods, a cooperative local, state and federal program aimed at the enhanced prosecution of gun crimes. The case was prosecuted by Assistant United States Attorney Daniel C. Tvedt and was investigated by the Mason City Police Department, the Cerro Gordo Sheriff’s Office, the Iowa Division of Criminal Investigation, and the Bureau of Alcohol, Tobacco, and Firearms.
