Dale Scott Olten Sr. will spend almost all of the next two decades serving a federal prison sentence for possessing firearms illegally.
The Russellville man was sentenced Thursday by U.S. District Judge Nanette K. Laughrey to 19 years and seven months in federal prison, without parole.
The U.S. Attorney's Office for Western Missouri noted in a news release that Olten was sentenced as a career offender, due to his prior felony convictions.
Olten, 47, pleaded guilty on Feb. 12 to being a felon in possession of a firearm, and to possessing stolen firearms. He admitted he was in possession of 29 rifles, shotguns and handguns on Feb. 27, 2009.
The firearms were discovered when law enforcement officers, investigating a series of burglaries, executed a search warrant at Olten's residence.
Under federal law, it is illegal for anyone who has been convicted of a felony to be in possession of any firearm or ammunition, and Olten has prior felony convictions for burglary, resisting arrest, stealing and receiving stolen property.
Olten also admitted that 17 of those firearms had been stolen.
The news release noted the case was investigated by four Mid-Missouri sheriff's departments - in Cole, Moniteau, Miller and Moniteau counties - as well as by the Missouri Probation and Parole Division and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.
He still faces other state charges, in cases transferred from Cole County to Phelps County. No trial dates have been set.
Olten was in prison on a state drug conviction when his 9-year-old daughter, Elizabeth, was killed in October 2009 near Jefferson City.
Alyssa Bustamante, who was 15 at the time, was charged as an adult with first-degree murder in the death of her young neighbor. Bustamante has pleaded not guilty and faces trial next May.
