12-year old Idaho boy shoots and kills his father

A 12-year old Swan Lake, Idaho boy has been arrested for the shooting death of his father.

From the article:

Deputies found the body of 46-year-old Paul Danielson. He was shot and killed inside the family's home.

They interviewed Danielson's 12-year-old son at the sheriff's office and during that interview, they took the boy into custody.
....
"He is being held on a homicide charge," said Bannock County Chief Deputy Prosecutor Vic Pearson. "However, since we are so early in the investigation, we need to get to a few more of the facts before we determine what charges exactly are going to be appropriate. However, we are holding him in custody based upon the initial investigation our sheriff's detectives have completed." 

The sheriff said they have the weapon, but won't say what type of gun was used.

Another big question that the sheriff said he can't answer is why this happened or what the boy's motive might have been.

Every gun in the hands of a child must first pass through the hands of an adult.
