"If you talk to the people who witnessed this, they're still troubled by it. They were bothered by what took place and how vicious this person was to this very small dog."The Society for the Prevention of Cruelty to Animals Los Angeles (spcaLA) is horrified by the violent crime."This guy is probably way more dangerous than you would think. It's not just a dog, because when you see violent behavior, it transcends the target that they are focusing on minute to minute. This could be a dangerous guy," said Madeline Bernstein with spcaLA.If you have any information about this case, you're urged to call Detective Reyes at (213) 486-0450.
