Offender: Troy Graves, 29, US Air Force service member
Victims: Shannon Schieber, 23, University of Pennsylvania student (rape/homicide), multiple rape victims in Pennsylvania & Colorado

Circumstances: Shannon Schieber was enrolled as a Phd. student at the Wharton School of Business, on May 7, 1998, Shannon was studying for exams when a neighbor heard what sounded like cries for help, he called 911 to report that his neighbor was asking for help, the police arrived but no one answered the door and the neighbor backed off his statement, they searched the property and the neighbor said it could have been outside so they left, Shannon’s brother showed up the next day and Shannon didn’t answer the door, the neighbor told her brother what he heard the night before, they broke into the apartment and found Shannon naked on her bed, Shannon was strangled to death and it appeared she tried to fight off her attacker, police found DNA at the scene, DNA ruled out those close to Shannon, Shannon’s parents were outraged that the man who killed their daughter was in the apartment when the police knocked on her door, but the police did their job right and by the book, a few days before the murder, Shannon reported being followed home one night, she was scared, so police started investigating the stranger angle, perhaps this is a serial rapist, they look into sex crimes in the area, they want to match the DNA to other sex crimes in the area.

In February 1999, they got a DNA match, 2 other sexual assaults had occurred but they were coded as misdemeanors, the assaults occurred just a few blocks from Shannon’s apartment, in June and July 1997, two more sexual assaults were connected to the offender bringing the total to 5, the PPD coded these sexual assaults as misdemeanors as well, they downgraded the offenses because it lessoned the load for the police, and made the arrest rate look better than it was, Shannon’s case helped enact change in Philadelphia, if they had investigated these cases, everyone would have known there was a serial rapist, Shannon would not be dead if she knew what was going on, the DNA still didn’t have a match to the offender, in 1997, a sketch was drawn from the recollections of the first victim, they got a new composite, this offender would enter the home, hold the victim down on the bed, rape them or make them perform oral sex, it was about control and domination for this guy and he was also somewhat of a romantic, once they acquiesced, he would treat them like a date, he would get comfortable with the victims, they determined he was a light skinned black male based on information he shared with one victim about his life growing up with bi-racial parents.

He was dubbed the Center City rapist, in August 1999, no other cases were reported since Shannon’s murder, the case went cold, the police got a bulletin in 2001 from Fort Collins, Colorado, the offenders modus operandi sounded familiar to the Philadelphia PD, on June 13, 2001, one victim was home when she was attacked from behind and raped, after she acquiesced, the rapist became gentle as if he was a boyfriend, after he left, she called 911, she was his third victim in Fort Collins, they were all blitz attacked, FC police were investigating a serial rapist, a fourth & fifth rapes were reported, he made a mistake and left behind a ball cap at the fifth victims home, Fort Collins DNA was matched to the rapes in Philadelphia, PPD gave FCPD the composite drawing, police received a letter in the mail from the suspect, he was taunting them, in the fall of 2001, the attacks in Fort Collins stopped, meanwhile the PPD started focusing on cross referencing names of suspects with the two geographic locations, they got a match for Air Force service member Troy Graves, he was in Philadelphia, Fort Collins, and now at Warren AFB in Cheyenne, Wyoming, in 2002, the police had the new suspect in their sites.

The police learned that Troy was also investigated by the Office of Special Investigations, it was over charges of harassing a female colleague, the charges were dropped but there was still something suspicious there, Graves has a clean criminal record and no finger prints on file, the case was circumstantial, they reached out to Graves to come to the police department and do an interview, Troy Graves and his wife showed up to the Fort Collins PD, the police immediately separated the couple, his wife admitted that he had insomnia and went for walks and drives at night and that honestly she thought he was having an affair, meanwhile Troy denied knowing anything about the crimes, the police confronted him about the rapes in Fort Collins, he denied being arrested for any sex crimes, he denied being investigated by the Air Force, he did not want to provide his fingerprints but a warrant was issued to compel him, the fingerprints were a match, Troy Graves was arrested and booked into custody on April 23, 2002, this case changed the PPD policies on sexual assault to include how evidence is handled and how the victims are treated and interviewed.

Disposition: Troy Graves feared a trial would not go in his favor in Fort Collins, Colorado, he pleaded guilty in exchange for a life sentence without the possibility of parole; Pennsylvania wanted to seek the death penalty but Shannon’s family did not want that because Shannon wouldn’t have wanted that, Graves entered into a plea agreement and got life in prison plus sixty years
