Seventeen-year-old Kara Allen, a National Honor Society student and varsity cheerleader, was killed at her Dearborn Heights home on September 21, 2016. The slaying occurred during a horrific attack carried out by her stepfather, Gregory Green, who also killed Kara’s 19-year-old brother Chadney Allen and their two half-sisters, 5-year-old Koi Green and 4-year-old Kaleigh Green.

Green called 911 and was waiting on the porch when police arrived. He had a prior conviction for the 1991 murder of his first wife, for which he served 16 years before parole.

The family’s loss is immense and many questions remain about how this family tragedy unfolded. If anyone knew Kara, Chadney, Koi or Kaleigh, or has information about the events that night, please share what you know with the thread.
