Sarah Butler was a 20-year-old New Jersey City University student and dancer who disappeared from her family’s home in Montclair while home for Thanksgiving break. On November 22, 2016, she met an online acquaintance after exchanging messages that included her asking, You’re not a serial killer, right? Her family reported her missing on November 23 when days passed with no word.

Friends and family used her social media to identify the man she had contacted and lured him to a public location where police were waiting. On December 1, 2016, Butler’s body was found concealed under leaves and debris in Eagle Rock Reservation in West Orange. An autopsy determined she had been strangled to death.

Cellphone data placed 20-year-old Khalil Wheeler-Weaver with Butler on the night she disappeared and at the site where her body was found; investigators linked him to two other recent killings and to an attempted murder and sexual assault of a surviving woman.

If anyone knew Sarah, the people she spent time with that Thanksgiving, or saw anything in or around Montclair or Eagle Rock Reservation that week, please share what might help the investigation.
