PUKWANA, S.D. -

Law enforcement authorities in Brule County have detonated a homemade explosive device found in a rural Pukwana home.
    
Law enforcement officers discovered the explosive device Wednesday when they were searching the home.
    
Chamberlain Police Chief Joe Hutmacher says the device was detonated at Brule Bottom, a public hunting area about seven miles north of Chamberlain.
    
Officers dispatched to the Pukwana home Wednesday were looking for 42-year-old Donald Pickner, who is yet to be located. Pickner was scheduled to be sentenced Friday on a federal charge of possession of firearms after a prior felony conviction. A warrant was issued after he did not show up.
    
The newspaper reports it wasn't immediately clear what charge led to the search of Pickner's home.
