Salinas police said the boy showed no remorse as he was arrested on suspicion of felony cruelty to an animal.
Events leading to his arrest began Friday afternoon, around 4 p.m., when someone called 911.
The dispatcher heard a female voice.
“He's hurting the dog,” said the caller, who could be heard struggling with someone. KSBW
has reported that the female caller is the boy's sister and that she fled the housing unit with the family's other dog.
She hung up, and police went to the location of the call – an apartment on the 300 block of Front Street.
The occupant refused to open the door, so officers got a pass key.
Inside, they found a terrier mix dog – about 12 pounds – hanging by its collar from a bedroom door handle.
The 12-year-old boy came out of the same bedroom.
According to a news release
, the child, showing no remorse, told officers "I was mad at the dog so I killed it."
