Animal-cruelty charges have been dropped against a former veterinarian's office employee who was caught on camera slamming a dog against a wall in 2013.

According to WFTV in Orlando, Stefanie Stasse was fired from the Orange County veterinarian's office where the alleged abuse happened. Deputies investigated the case and turned it over to the state attorney's office, which filed two animal-cruelty charges against Stasse.

WFTV learned those charges were dropped Monday after prosecutors had issues with key witnesses in the case. The State Attorney's Office said those witnesses were fellow employees at the time.

Video of the incident was posted on YouTube and showed the dog being slammed against a wall as many as five times.
