Amber Hagerman's Bicycle

Origin
Amber Rene Hagerman (November 25, 1986 – January 17, 1996) was abducted while riding her bike in Arlington, Texas. A neighbor who witnessed the abduction called the police, and Amber's brother Ricky went home to tell his mother and grandparents what happened. On hearing the news, Amber's father Richard called Marc Klaas, whose daughter Polly had been abducted and murdered in 1993.Richard Hagerman and Amber's mother, Donna Whitson (now Donna Norris), called the news media and the FBI. The Whitsons and their neighbors began searching for Amber. Four days after the abduction, a man walking his dog found her body in a storm drainage ditch. Her killer was never found, and her homicide remains unsolved.

Effect
When someone rides the bike, they will disappear, and the bike will find a new victim. The victim will be found dead a few days later.
