Aimee Willard

Because of the bureaucratic issues which allowed Bomar to remain free to commit these crimes, The Victims of Trafficking and Violence Protection Act (H.R. 3244), better known as "Aimee's Law", was passed by the US Congress by a vote of 90-5 in 2000 and signed into law by President Bill Clinton on October 28, 2000. It encourages states to keep murderers, rapists, and child molesters behind bars longer, and holds the state financially accountable if it fails to do so. It allows interstate parole violators to be jailed in their state of residence at the expense of the state where the original offense was committed. It also allows for offenders to be jailed in another state if circumstances allow.

The case went cold for nearly two years, during which time many theories and suspects were investigated. The case was re-opened when another woman in Pennsylvania was hit from behind while driving alone at night. The driver of the other vehicle tried to get her to stop, but the woman refused and instead memorized his license plate number. That plate was registered to Arthur Bomar, but the car belonged to Maria Cabuenos, another Pennsylvania woman who had been reported missing in March 1998. Bomar's actual car was later found at a junkyard. The burn pattern found on Willard's back was consistent with the oil pan on the bottom of Bomar's car. Moreover, Willard's blood and hair were found in Cabuenos' car, which Bomar had been driving.

Willard was a star lacrosse player at the Academy of Notre Dame de Namur in Villanova, Pennsylvania and later at George Mason University. In 1996, Willard led the Colonial Athletic Association in scoring with fifty goals and twenty-nine assists. She was named to the All-Conference Team in both soccer and lacrosse, and to the All-American team for the Southeast region in lacrosse that year. US Lacrosse has created a national award in her honor.

With DNA evidence, Arthur Bomar was identified as Willard's killer. He was an ex-convict who had been convicted of second-degree murder in 1979 in Nevada; he was paroled 11 years later. Bomar had repeatedly violated his parole but was never returned to Nevada to finish his sentence, due to that state's failure to arrange and finance extradition.

Aimee Ellen Willard (June 8, 1974 – June 20, 1996) was a college lacrosse player who was murdered near Philadelphia on her way home from a night out with friends. Her car was left running, with the lights on and driver's side door open, on the Exit 5 off-ramp of Interstate 476. Her body was found the next day in North Philadelphia, 17 miles away. She was beaten to death with a tire iron. The beating was so savage that her skull had multiple fractures. The then-unsolved crime was featured on Unsolved Mysteries and later as a solved one on Cold Case Files and The New Detectives. The story of her murder and investigation was also featured on an episode of Forensic Files as well as in the film "The Dark Side of Parole."
