A Pakistani doctor, living in Ohio, obsessed with photographing young women has been charged with raping and killing a pregnant 23-year-old after she responded to an ad on Craigslist

Pakistani-born Dr Ali Salim murdered Deanna Ballman, of Pataskala, and her unborn baby during the summer of 2012 by injecting her with a lethal dose of heroin and then doing inhumane things to her corpse. Ballman, who was nine-months pregnant and had two kids at home, was found dead in the backseat of her car in woods outside of New Albany on August 1, 2012. Salim, 44, pleaded not guilty today to two counts of murder as well as rape, felonious assault, corrupting another with drugs, kidnapping, tampering with evidence and abuse of a corpse. He is expected to be released on $1 million bail. According to Ballman's family, the woman was responding to a housecleaning ad and called to say that she wasn't feeling well, which was the last they heard of her. However, reports suggest that she may have met with Salim after he put a call out for models. Salim has been at the center of the investigation into Ballman's death for months. Investigators had searched the doctor's Ohio home and removed a laptop, camera and other items.
