On the night of August 5, 2020, a deliberate fire destroyed a suburban Denver home and killed five members of a Senegalese family, including 6-month-old Hawa Baye. Also killed were Djibril Diol, 29; Adja Diol, 23; their 22-month-old daughter Khadija Diol; and Hassan Diol, 25. Three other occupants escaped by jumping from a second-story window.

Surveillance showed three suspects in dark hoodies and full face masks. Investigators traced internet searches of the house’s address to identify three suspects: Kevin Bui, Gavin Seymour, and Dillon Siebert, who were arrested about five months after the fire. Prosecutors described Bui, then a teenager tried as an adult, as the ringleader; the motive was reported as a mistaken act of revenge after Bui tracked a stolen phone to the wrong address.

Anyone with information about Hawa Baye or the Diol family or who saw activity near that home in early August 2020 is asked to come forward.
