Boise man pleads guilty in accidental shooting of cousin

December 19, 2013 

— A 24-year-old Boise man who accidentally shot his cousin in the head pleaded guilty to involuntary manslaughter Wednesday.

Derick Lee Sedivy had been drinking at an Orchard Street home the night 20-year-old Austin Tyler Blankenburg was shot May 10. Blankenburg, a Kuna resident, died the next day.

Police classified the shooting as unintentional, and pointed to alcohol as a factor. Sedivy was arrested and charged with involuntary manslaughter and use of a deadly weapon during the commission of a felony.

He pleaded guilty to the involuntary manslaughter charge Wednesday, less than a month before the set start date for his jury trial. The deadly weapons enhancement, which could have added 15 years to Sedivy's sentence, was dismissed when he pleaded guilty, prosecutor Brent Ferguson said.

Sedivy could face up to ten years in prison for involuntary manslaughter. Ferguson said the prosecution will recommend a sentence of one year in jail, followed by ten years of probation.

Sentencing is scheduled for Feb. 7 in front of Judge Patrick H. Owen.
