To Bugs

My first pet was a lop-eared rabbit we named after Bugs Bunny. Someone let themselves into our garage and killed him with a hammer. The original manuscript was handwritten in capital letters.

Liquid strands of warmth fly (flutter)
Through the frosted air
Innocence lurks in a box
Thwarting death's rusty snare
A knock, a whisper, someone calls
The lock bits tumble (clack)
An outstretch hand, a hammer raised
And a child's joy falls slack
Discovery, and sorrow fills
The hearts and minds of all
"Who did this?" is the question asked
As tired voices rise and fall

My family has an idea who did it, but we were never able to prove it. RIP, Bugs!
