UPDATE: Authorities have charged 20-year-old Alvin Wallace with animal cruelty. If convicted, he will face a fine of up to $5,000 and/or up to five years in prison.
OKLAHOMA CITY - A man is behind bars accused of killing his girlfriend's pet during a fight.
Police said it's not something they've seen before, at least not that they remember.
A chinchilla killed, the helpless victim in a fight between two adults.
Master Sgt. Gary Knight said, "Animal cruelty is something we see from time to time, but I've never seen one involving a chinchilla."
Monday night Oklahoma City Police were called to an apartment complex near Northwest Expressway and Meridian.
A fight between a man and his girlfriend had escalated.
Police said during that argument, the woman's boyfriend, 20-year-old Alvin Wallace, grabbed her pet chinchilla and threw it to the ground.
Wallace was arrested and booked into the Oklahoma County Jail.
Knight said, "Obviously picking up an animal like that and slamming it to the ground is at least going to injure it and in this case it caused its death."
We went to the apartment where Wallace lives and his mother answered the door.
She did not want to be on camera but told us she has since told her son and his girlfriend they need to find a new place to live.
She said she is heartbroken the animal died in such an awful way but she said her son is not the only one to blame.
She said his girlfriend had thrown the animal at him.
It's an allegation police said they cannot confirm.
Knight said, "At some point the male grabbed the chinchilla and threw it to the ground ultimately causing its death."
We tried to find Alvin Wallace and his girlfriend; however, we were unable to track down either one of them.
