had been cut off. An autopsy revealed that she had been beaten and sexually assaulted before being asphyxiated. According to forensic psychologist Dr. Stephanie Stolinsky, the killer "tried to dehumanize her completely. ... Whenever you hide someone's face, it means that you don't want to see them as a human being. You want to pretend that they're just an object". The murder case of Imette St. Guillen was handled by the Special Victims Squad and Brooklyn North Homicide Squad of the NYPD. Arrest Darryl Littlejohn, one of two bouncers at The Falls where St. Guillen was seen the night she was murdered, was charged with first-degree murder, kidnapping, and unlawful imprisonment. DNA that was proven to be Littlejohn's, most likely caused from a nosebleed, was found in blood on the plastic ties used to bind St. Guillen's hands. Littlejohn was asked to escort St. Guillen out of The Falls just before closing, and was later seen talking to the young woman in front of the bar. His basement apartment in Queens and vehicles were searched by police and crime scene investigators. Carpet fibers found in Littlejohn's home were a match to fibers discovered on the adhesive tape wrapping St. Guillen's face. Additional evidence that Littlejohn was in the area at the time, date, and place where St. Guillen was killed and dumped was found using cell phone tower records. These "indicated movement from his home to near the spot in Brooklyn where Ms. St. Guillen's body was found." Due to the nature of St. Guillen's murder and other high-profile crimes, The Village Voice suggested that the Internal Affairs Bureau (IAB) was devoting more of its time to tracing the cellular phones of detectives. The article discussed efforts to uncover leaks to the media in these cases. A source that communicated with The Village Voice said that police in St. Guillen's murder case had received "punitive 'letters of instruction' in their files and were docked days of pay." Littlejohn, an ex-convict, had spent more than 12 years in prison for drug possession and robbery charges. He was on parole at the time of his employment at The Falls and, by working late hours at the bar, was violating the curfew of his parole agreement. He was initially held by authorities because of the parole violation, and was later charged with one count of first-degree murder and two counts of second-degree murder
