Caroline Wimmer was found strangled to death with a hair dryer cord in her apartment March 30.
Mark Musarella was allegedly one of the EMTs who arrived at the scene of the crime.
According to FOX 5 in New York, Musarella decided to take a photograph of Ms. Wimmer's body. He then posted it to his Facebook page.
Richmond University Medical Center officials saw the posting and fired Musarella, but refused to give reasons for his dismissal. However, the Staten Island DA is investigating the matter, according to Fox 5.
